Every cell, virus, plant, or animal mutation or characteristic is explained by Natural Selection.
It’s almost like there is some motivation for it to make sure life exists and survives. But why do anything at all? If there is a God then it makes sense that it was put in place for life to exist but if there is no God then why don’t we just have a universe of non-living matter?
You have a lot of terms conflated in a way that tells me you would benefit from learning more about these ideas.
Natural selection is the opposite of a motivation. All it really is this: Traits that help an organism live to reproduce or do not adversely affect its opportunity or ability to reproduce will continue to propagate in a population of organisms. Traits that hinder an organism in reproducing or adversely affect its opportunity or ability to reproduce will gradually be expressed less. There isn’t a motivation for that, it’s a self-selecting process. If an organism can’t reproduce, it can’t pass its traits on to the next generation. If it can reproduce, it can pass its traits on to the next generation.
Life isn’t motivated to survive because an omnipotent superintelligence wants it to be. All the life that didn’t give a shit about surviving didn’t live long enough to propagate.
Natural selection does not provide an origin for life or the universe. I agree with the other poster who mentions that organic matter - and life - is a result of the basic nature of matter in the universe. I wouldn’t say I know much about the origin of the universe, but inserting a god into it just kicks the can down the road. Every issue you might have with the big bang is just moved one completely unverifiable step away by throwing a god into the equation. Who made god? And, if god can exist without being created, why could not the universe?
