You alluded to unspecific differences in bone structure we might see if gravity were somehow much greater or lesser.
It was not unspecific. I made specific statements about how the sizes of the bones and the bone density would change in differing levels of gravity.
You gave no details and it was basically a strawman argument because gravity on earth is really not an issue!
Gravity was not an issue? Are you saying that gravity is not one of the things that changed?
We might look at the possibility that gravity at times may have been able to be greatly mitigated or impacted.
And by an amazing coincidence, gravity was mitigated by the EXACT amount required to produce life forms that look exactly like what we would expect to see if the laws hadn't changed at all. Are you going to keep invoking coincidence to support your preposterous claims?
So you don't know? This is all just a guess?
So lemme get this straight...
You are insisting that we take your guess seriously, despite the fact that there is no evidence for your DSP idea, you can't specify what laws were different, you can't specify HOW they were different, you are incapable of proposing any mechanism for such a change, you can't explain why things from before the alleged change fit with present laws... And you expect us to take you seriously?
After all we don't really know if the moon was the same distance, or if planets or space bodies perhaps used to have orbits that affected earth..etc. Again, you do not know. Add that to the list of things science is truly in the dark about. Thanks for that.
If the moon was at a different distance, then we would see fossil indications of different tidal effects. Yet there are no indications at all that the moon's distance from earth has been changing in any way other than the way we already know it is.
Not only can science not describe nature as it was, but it has no clue whether nature was the same or different!
You keep making this claim. Maybe one day you will surprise us all and post some evidence to support it.
The bible does describe the world in the past in some detail. The world described simply differs fundamentally in many ways from the world and nature of today.
So you've just decided that the Bible MUST be literally true and you've come up with a fanciful idea to try to explain it.
It would be hypocritical to expect anyone to describe how God changed any forces or laws. The only thing that matters is whether He did change things. If He did, then the whole foundation and basis that science uses for all models of the far past and origins is laughably and fatally flawed.
And if he didn't, then your whole thing collapses like the flimsy house of cards that it is.
Maybe that is part of the reason birds today do not reach anywhere near the size some birds used to reach. But as explained gravity is really not an issue. We don't really know if there was any small difference or not. Looking at some ancient structures, it would make sense to me that gravity was somehow able to be reduced.
Wow, you sure do like shooting yourself in the foot, don't you?
Literally five seconds on Google was enough to tell me that the largest flying bird ever was
Argentavis. It's size has not been able to be precisely measured, since the single specimen we have of its arm is damaged, but current estimates put it between 5 to 6.5 meters. Even so, its weight would have been only about 70 kilograms or so, about the same as an adult person (and a fairly light adult at that - for a point of comparison, my husband is high nineties).
But the bit that completely destroys your argument is the fact that it lived between 9 million and 6.8 million years ago.
Now, if - as you claim - the present laws came into effect at the time of the KT boundary, then this bird was living in the present state! The KT boundary was 65 million years ago - so when these birds appeared,
it had already been the present state for more than 55 million years! Thus, these massive birds prove that such large flying creatures could exist in the present state! No past state required!
And just to hammer that final nail into the coffin, ALL of these massive birds are built according to present state laws of aerodynamics. We NEVER find any of these birds with structures that don't make sense according to present scientific understanding.
Once again, this bird lived 25 million years ago - well into the present state.
" This formidable predator may have had a wingspan of 36 feet—close to the size a small aircraft.."
Ancient Winged Terror Was One of the Largest Animals to Fly
"
Quetzalcoatlus northropi evolved a ridiculous 40-foot wingspan, cinching the record for the largest flying animal to this day."
https://motherboard.vice.com/en_us/...gest-flying-dinosaur-was-a-four-winged-raptor
And funnily enough, the body plans for these creatures, ratios of wing length to body size, etc, are all EXACTLY what we'd expect to see if they were flying in a sky that operated according to our current laws of nature.
"
Several recent estimates put
Quetzalcoatlus northropi at
approximately 250kg.
Palaeontologists still have many questions about giant pterosaur flight. We
don’t fully
understand how they took off or what kind of flyers they were once in the air. Did they flap or soar? How long could they fly for? How did they land? In fact, some people still believe these giraffe-sized animals were too heavy to fly at all. "
Pterosaurs should have been too big to fly – so how did they manage it?
So science does not understand. If there were some aspect of nature in that day that was different, perhaps that would help the giants. We don't know. We do know they would not seem to make sense in this world today.
Did you even bother to read the article? It answers many of your questions. Of course, you like to quote mine, and take the fact that there are a few people who disagree and pretend that means that science has no idea at all. That's not very honest, is it?
I look at an airplane that weighs 162 kgs. Then I wonder about some bird over 250 kgs!
"The Guinness World Record title of smallest and lightest turbofan-powered plane goes to the
Bede BD-5, which has retained the honour since 1971 with its featherlight weight of
162.7 kg."

Wow, it seems like you are being deliberately deceptive here. Your source says, "...that 10–11 m wingspans and masses of 200–250 kg are the most reliable upper estimates of known pterosaur size."
UPPER ESTIMATES.
That means that they could have been lower. But here you are claiming that all the animals weighed about 250.
I mean, I could say that the upper limits on the weight of a person can be 300 to 400 kilos ( there have been
several people who have weighed over 600 kilos - more than half a ton). But the
average weight of an adult is about 60-80 kilos. Now, of course, we are unlikely to see such a large discrepancy in the wild between the average size and the maximum size, but it will still be there, and it is rather dishonest for you to present the maximum size as an average size.
And once again, I will point out that the body structure of all these massive flying creatures fits exactly with what we would expect if the laws of aerodynamics were the same back then as they are today.
Speaking of crocodiles they found one up (fossil remains) in the arctic, so there again, we see things changed a lot!
It's called plate tectonics, I thought everyone knew about that. We literally have lots of evidence to explain why there were reptiles there - different atmosphere had created a greenhouse effect, raising temperatures.
With other creatures that are small and also exist today, the question arises..'if man shared an ancestor with the flatworm, why is it that we see the creatures unchanged since the dawn of time!?'
Because they are well adapted to the niche they inhabit and the selective pressures that would drive them to evolve and change have not changed much for a very long time. If there are no changes in selective pressures, then once an organism is well adapted, it isn't going to change much.
Honestly, I don't know how you expect to be able to have a discussion about evolution when it is clear that you lack even basic knowledge about it.
So what!!? I don't care if they did...
And that's the problem right there, isn't it? You've just admitted that you don't care about what the evidence shows, you are just going to deny everything that disagrees with your preconceived ideas. That is the literal definition of "closed-minded".
...and then evolved in some cases BACK to birds! Fine with me. You see, the birds were created, and if dinos evolved from birds (and also into birds again later) all that would mean is that dinos were not created kinds but adaptations and evolved from created kinds! That would explain why none were in the ark also. God called the kinds into the ark. ( I suspect most dinos were extinct before the flood, but if any were still here, they would probably not have been invited)
Did you even bother to read what I wrote?
I never said that dinosaurs evolved from birds.
I said that birds evolved from dinosaurs.
As explained above, it is not that they disprove the theory of man evolving from a shared ancestor with flatworms, but it shows that the worms are unchanged since creation!
I've dealt with this.
Not just conditions. In the former nature creatures could rapidly evolve and adapt for conditions.
If the animals were changing so much, why are you making such a big deal about how flatworms have not changed at all?
So seem to be see-sawing wildly between to contradictory ideas:
- Flatworms haven't evolved at all, so evolution is bunk!
- Animals could evolve much more rapidly than they do today!
You seem incapable of keeping your own story straight and instead just pick and choose your position about this based on whatever you are saying at the time. Your inconsistency points out the fatal flaw in your entire argument.
Nature itself was probably different.
Different how? Be specific.
The laws that govern how atoms behave for example.
In what way were these laws different? What were the differences in the way atoms behaved compared with how they behave today?
The forces and laws that determine how DNA works. etc etc.
In what way were these laws different? What were the differences in the way DNA worked compared with how it works today?
In common English let me interpret that for you. Some (probably not original kind birds but adaptations from kinds) birds that could leave remains did leave fossils in that time. It is not that birds evolved from the sorts of birds we see fossilized in that time! The opposite is likely true, that the birds that evolved from the created kinds are possibly the sorts of birds that COULD fossilize!
Right, so the birds we have today did NOT evolve from the modern looking birds that fossilized.
But they just coincidentally evolved to look just like they had evolved from the fossilized birds.
Once again, you need to rely on coincidence.
And, I'm going to point out that despite all the claims you've made, you've been unable to present any evidence to support your position. This makes the eighth such post. I'll admit that you did try to present evidence, but you said the evidence was regarding an animal from the different state past, yet I showed that it was actually from the present state - according to what you said in post 1399.
Your arguments continue to fail.
