I suspect you have got some skewed information about the Cambrian explosion. The first life of the Cambrian wasn't much like modern life. For example Cambrian "fish" were basically swimming tubes with just the beginning of a spine.
Thanks for such a nice reply.
I don't believe I have a skewed idea about the Cambrian Explosion. Of course, I'm not going by the same information you have. I explained my view in another post...I don't understand how we get from one stratos to the other and I don't see links in between. I'm going by images of the different time zones and the different stratos. I admit that there must surely be something I don't see since I'm sure it's much more complicated than any images makes it seem.
But, yes, how does "TUBE" get to be a "FISH"?.
I just think this is too complicated and given any amount of time it just cannot happen. I do, however, realize I may be wrong about this...but some scientists seem to agree.
But as to explanation, it wasn't beginning of all life... it was the beginning of the ability to find evidence of life.
I agree with micro evolution. I think everyone does. It's obvious to all. This would be adaptation, or the survival of the fittest, or selection, etc.
But some add to this the beginning of life...
I find this to be a totally different argument.
If we understood HOW life began,,,why could we not reproduce it? Surely there must be a reason...maybe it's just not doable?
There is evidence of a variety of life in the Pre-Cambrian, but it is all very soft bodied. Preservation is rare to begin with and preservation for more then 500 million years rarer still.
So the Cambrian explosion just shows when life stated using calcium and other elements to make coverings or internal structure of cartilage or later bone.
It's like finding foot prints in the soft mud next to the pavement... it's not that the people suddenly teleported there, it's just that you couldn't detect where they walked on the footpath.
Interesting!
I think I understand better now.
The footprints in the mud would have disappeared,,,but not the ones on the pavement.
I'm curious about what you think occurred? Were the simple squidgy things of the Cambrian created... then destroyed only to be replaced hundreds and hundreds of times over the eons?
I don't know how it all happened.
I just can't discount ID, or, as I like to call it...God.
Yes, maybe he just loves to create...
maybe He was creating a good earth for us to live in.
Maybe He's still creating....so many galaxies...
(I know this sounds silly to you).
You are mistaken, the Theory of Evolution has never been used as an explanation for the origin of life.
It's the Origin of Species... life already existed, but it diversifies into new species via evolution.
Yes, it's that changing into different life forms that gives most creationists a problem...and even some atheists. Maybe one has to be a scientist to be able to understand this.
Science latches onto it because it works, both as an explanation of evidence now and in the past... and as a method that can be use in other fields of science and engineering.
The problem with your "Some scientists" who have left the theory, is that I have never seen any that could present scientific evidence for their doubt.
Maybe they don't know the answer but have been convinced that species change into a different species? I could not like taking a certain medicine, but have nothing to replace it with. I don't have a problem with needing to know another solutions before I leave one I don't accept.
People in this thread have presented the evidence. It's already completely "proven".
Hmmm. How come every scientist agrees that gravity exists? But they don't all agree with this idea of species changing..
I'm not that old, but I think you got some bad information in the 60s. I'm pretty sure that both the age of the Earth and in particular the age of Cambrian explosion were well established by then.
The evidence of the Earth seems to be that simple life got going pretty quickly after the surface settled down... but it's also not really relevant.
Yes, in the 60's the age of the earth was already established. This is NOT what I was referring to: I was referring to the existence of t he universe.
It was believed that the universe ALWAYS EXISTED...that it had no beginning. Then the BB was generally accepted. I might have mis-spoken.
Unless people can demonstrate that the natural beginning and development of life is literally impossible, then the shear scale of the universe squashes probability arguments.
People DO try to demonstrate that life can be created in a lab. Isn't the fact that this cannot be done proof enough that the beginning of life is not possible without some "spark" that may very well be metaphysical?
Most people already do. In fact, I'm pretty sure that Christians who accept evolution and the Big Bang outnumber atheists of all stripes.
An intelligent designer as an explanation for the universe can be very appealing and convincing... it just doesn't provide any scientific arguments or evidence.
If you can't find evidence you can test, then you can't apply science to it. If not, it might as well be "That's just how it is, no one can know why."
A lot of cosmologists agree that time came about with the Big Bang, so they agree with you that there was nothing before, because before doesn't even make sense. Like north of the north pole.
Finding an explanation for the unknowable in personal conviction, tradition or personal revelation is 100% undisputable by science... it's when you start applying that to things that are known, or at least reasonably inferred it becomes a problem.
Maybe there are some experiences that are repeated and can even be tested,,,,but it may not be science and certainly is not accepted by the scientific community.
Can miracles be proven?
Can NDE be proven?
Why not?
