1. Matter, energy and life can't produce itself out of nothing. Even a cave man can understand that.
That's straw-man, omega2xx.
Evolution never state it create itself from "nothing".
Evolution required life to already exist, and with animals, genes are passed through reproduction, from parents to offspring.
Evolution is not about origin of first life. The origin of life is mainly the focus of abiogenesis, which is different to evolution. Evolution is focused in the area of biodiversity.
Clearly, your understanding is no better than that of cave man.
Natural Selection is about adaptation, where environment, such as climate, terrain, availability of food, etc, can affect the species.
At some point, tens of thousands of years ago, the brown bear species (Urus arctos), diverge because of the regions they were living. The brown bears that were living in colder regions, had to adapt, where trees don't grow, when ice sheets covered much of the northern regions of Europe, Asia and North America. But this Ice Age weren't as global as previous glacial era.
Those that remained in warmer regions remained as they were, but new species gradually arose from the brown bears, producing species that can survive in extreme cold, which we called polar bears (Ursus maritimus).
It is not just the white fur that make polar bears different from the brown bears, but the whiteness does help when hunting their prey, where they can hide among the ice. The polar bear developed fur (and hide) that's more water-proof and wind-proof than that of brown bear, so they can survive extreme cold, from wind or the sea they can swim. Brown bears cannot swim in sea.
Although, brown bear can swim in lakes or rivers, they preferred wading than swimming. I am sure you have seen documentaries of brown bears catching salmons; they do by wading, not swimming.
The polar bear's main source of food is sea-seals, which contained high fat contents. The polar bear has more fat than brown bear. If you remember your high school biology, body fat is what help animals insulate themselves from the cold. Because of the higher body fat in polar bears, they don't need to hibernate, like the brown bears, black bears and grizzly bears in the colder seasons.
The polar bears didn't come out of nowhere, omega. It is offshoot of the brown bears.
That's Evolution by Natural Selection at work. A biologist who focused on evolution between brown bears and polar bears would not need to know how life started billions of years ago; they would only need to trace back evidences that go back a couple of hundred thousand of years.
Another example is viruses. Virologists who study viruses and developed vaccines or antibiotics, would only focused viruses of this century and the last century (20th century), because it is not that cultured viruses several centuries or millennia. So virologists and vaccine researchers need solid understanding of evolution, via Natural Selection and Mutation. Vaccine being used, will make future strains of viruses resistant or immune to that viruses.
For you to say that there are no evidences, when it staring at you in the face, only demonstrated your ignorance, or worse, your dishonesty at ignoring or dismissing the evidences.
No, omega. You don't understand evolution and abiogenesis at all.
If you understand science (not just biology) at all, you would know that they rely on evidences to verify or refute explanation, not proof. Proof and evidence are different to both scientists and mathematicians.
And there are plenty of evidences to support evolution. Abiogenesis, on the other hand, is still relatively young theory, with not as much evidences as there are in evolution, but their focus are different.
