Since I am a chemist you really are taking a lot for granted.
You miss the point .
The simple limitations of our own abilities make it impossible to accept that we cannot answer some very basic questions.
OK scientist tell me (NO THEORIES ONLY FACTS WILL BE ACCEPTED)

What wiped out the dinosaurs?
What is real ?
How many different species are there on this planet ? Don't forget new ones are discovered all the time .
Why do people feel they need to believe that some force created us and everything ?
Why couldn't we all be figments of our own imagination ?
Why couldn't we simply have popped into existence?
Maybe you would know if you were insane and imagining everything and maybe you would be so deluded that you believed what was in your mind but in reality it could all be a dream.

Get where I'm coming from yet ??
Science can't, nor do I believe it ever will be able to answer all questions.
Our human limits make us prone to mistakes and on numerous occasions science has had to admit to getting it wrong.
