My whole life! Its's experiences .. including (but not exceptionally), education, travel, logical deduction, other people..
Where do you get
YOUR knowledge of what's around you?
ie. the meaning of our existence
If one comes to the forum with a preconceived idea that
all religions (belief in God) is made up, then how do they expect to see otherwise? They have no interest in what (a possible) God might be saying..
How do you expect to "
verify" whether a religion is true or false?
Claiming there is no "
physical evidence" won't do, I'm afraid.
And naturally (according to disbelievers), '
second-hand' evidence, such as scripture won't do either .. must be all made-up
