I have said nothing of science. I am asking a simple question. Why would someone change there beliefs. Everyone starts off life not believing and some change.

I am not here to tell you that Science said this… and therefore your wrong.

I am saying, that it is not my job to prove you wrong. IT is YOUR (not you specifically) job to prove that “god created all things”. For example

I say:
I have a dragon in my room

My friend says
No you don’t. I don’t have any reason to believe that

I say
Prove to me you don’t have a reason to believe that…

This is because I made the statement of existence. You don’t have to prove non-existence it is just assumed.
