It hasn't been proved either way though, so believing there are not fairies or unicorns is part of my personal belief system or if you prefer, system of beliefs. Every person who can think has a system of beliefs.
It's amazing the mental pretzel twists people will try to claim are straight lines in order to equate using logic with believing invisible people.
Yes, you have decided that you don't believe in God. You have a belief that there is no god(s). It is not something anyone can prove right now, so you have faith that your conclusion is correct.
And how they will ignorantly, after many repeated correctections, try to tell people what they believe in order to make that house of cards built on a foundation of twisted logic stand up.
The belief that ther is a God is only relaised when we are finished this earthly life. It has no proof or requires evidence.
But at least they admit they are making it all up.
Theists, quit being ridiculous.
