All kinds of questions just get rehashed over and over. Evolutionist seem to think they are smarter. They all talk down to anyone that does not agree with there point of view.
There would be no new science if everyone believed the scientist
But a lot of times scientists are wrong or just don't know, but act like they know.
Here is some examples.
Dogs are color blind and only see in 2 dimensions.
Whatever. I would like to see the dog they interviewed. One bark for yes and two for no. If they can not look through a dogs eyes and use their brain to interpret what it sees they don't have a clue. It would be silly to watch a dog pounce 4 feet in front of their prey, because of no depth perception. lol They obviously have depth perception which would mean they see 3D not 2D.
The Earths core is molten magma.
They don't really know. No one has ever been there. It could be a mineral that has never been seen and can withstand great pressure without melting. We just don't know. But scientist claim that there right. The theory is plausible , but there is no physical evidence.
The expanding Universe. There is new proof, it is not expanding and accelerating. That puts a hole in the Big bang and the way we look at the universe. More like a Big I don't know what happened, but I'll make it sound good.
This is one web site. do a search on google for non expanding universe. You'll get tons of other plausible theories.

If a tree falls in the woods does it make a noise? According to my science teacher, it doesn't. Whatever. What makes humans so special, if we don't here it or see it. It must not exist. Of course the tree made a huge crashing noise.
So it comes down to Scientists are imperfect humans that don't know every thing and should humble themselves to new ideas.

All of your answers are plausible. But all lake scientific observation. We don't see it happen. We did not see the universe cool off and create hydrogen. Which than pulled together and made stars.
We did not see the bighorn get evolved by man to a fluffy wool sheep
We did not witness the inter breeding of fowl to make chickens.
According to science, if we were not there, It must not exist.
God Bless
