To say that something exists, it must first be perceived. If you do not exist, you cannot perceive anything. If you concede that something can exist long before the evidence of its existence is apparent, or perceived, then you should have no problem accepting the idea that God existed long before the earth was formed.<quoted text>
Why do you insist on thinking backwards. Evidence is there that something exists, you get the evidence long before the existence is apparent. You only know I exist because of the interactions that lead to the posts online, otherwise you have no way of validly asserting that I exist. My neighbor exists, I know this because I hear them moving about, the noise they make is evidence that they exist. I do not see my neighbor, and if there was no noise then me claiming they exist would be lunacy. The evidence precedes the fact, therefore, nothing is self evident.
The fact that you perceive something (noise or whatever) is self evidence that you exist. You perceive, therefore you are. I perceive your posts as evidence that you exist. I perceive your existence, therefore you are.
