You can not believe whatever you like.
I believe that Atheists have made a leap of faith and ignored the lack of evidence for the non-existence of God or Gods and put their trust in believing in Him/Her/They not existing (which is as close to not believing in Him/Her/They as to make no odds).
And it's okay because No God loves you wether you believe or not.
To know something fully one has to be omniscient.
One can only know for sure if every aspect of the lunar landing story is as published if you know for sure every aspect of the lunar landing story is as published.
I think therefore I think I think.
Any thing else is to some degree a personal opinion or belief either based on the facts as published or personally researched or regardless of any or how much of the facts you wish to ignore.
I encourage people not to take things at face value but to come to their own conclusions.
