"Amazing, they say without hesitation that complex life showed up 500 million years ago. And they know how?"
Science of various kinds. What, you thought they used a magic eight ball or something?
"That is totally historical science, not observational."
You don't actually have to directly observe things in science. Ask a physicist when the last time he saw a quark was or an astronomer when he last saw a black hole or a cosmologist when he last directly observed dark matter.
"There is no way to know that number, they admit they cannot be sure of their own theory but we are to believe 500 million years?"
Belief doesn't enter into it and who is saying they can't be sure of their own "theory", whichever theory you're speaking of.
"Layers of rock and mud formed with deposits of thousands of dead things all over the planet...hmmm..sounds like a global flood."

"God's Word is quite clear on this, He is the creator, evolution is a false religion trying to explain away God."
