This is a great example. You're using the word "we", either you lack critical thinking, or you seriously need help (or both).
Now, about "billions of years" of evolution.
I am sold on the idea that the earth is a few cars old, even as a Christian, it makes sense to me, same as the big bang.
However, organic evolution (not to be confused with "adaptability" or with "mutation") is a completely different thing.
The level of complexity on how everything works together, with very specific functions, in each organism all but debunks the idea that these evolved from nothing but a cell. It's highly unlikely that such complexity could arise from random mutations and natural selection. Additionally, as organisms mutate, the legacy organism gets left behind and replaced by the newer version. How do you explain that there are still monkeys around, but no cro-magnon or Neanderthal humans around? We mutated to what we are today, so those steps of the homo sapiens was just deleted and replaced by modern humans, who are still mutating (and probably will indefinitely).
Critical thi king requires understanding what the word "theory" means in order to allow our brains to keep searching for more evidences to either confirm or deny each theory.
At this point, creationism, evolution and everything in between are just that, theories, just like my arguments above, which is what makes me so certain that, when someone ascertains theories as absolute truths, usually because "scientists have found" (which scientists?) or "experts confirm" (who made them experts again?), those individuals lack critical thinking, which requires one to question everything (yes, even my faith) in order to attempt to reach the absolute truth.
Theory means "A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena." pay attention to the word "predictions", it's not the same as the reasons why it rains, which have not been theories for a couple of centuries, since there is nothing left to find, and the truth about rain works every single time, no exceptions.
So, you see? These are the reasons why the world is controlled by a select few, the ones that challenge theories, ask questions, and are not satisfied with anything except undeniable evidence.
Having said that, are you still sending me the valid and undeniable evidences?
