@Romeo Fabulini,
You're essentially quoting the Bible to prove its own validity. Surely you see the flaw in this reasoning? There's scarce evidence that Jesus even existed at all.
Actually, atheists don't have a set explanation for how the universe came into being (other than the already accepted big bang theory, but we don't know how or why it happened). Atheists are saying they don't KNOW how the universe was created. If I have an option between not knowing and god creating the universe, I take not knowing.
We're "guessing" that the Bible is not true? What do you mean guessing? The fossil record doesn't support it. Radiometric dating doesn't support it. History doesn't support it. Science doesn't support it. Literally nothing lies in favor of the Bible being true. There comes a time when it isn't a guess.
And if you're making an appeal to pascal's wager I will simply refute you with this: you are rejecting thousands of other holy texts and belief systems in your acceptance of one that is of equal invalidity.
In conclusion, you are guessing that the Bible IS true (being that there is no evidence for any of it), whereas I am almost certain most of it is hogwash (because unlike some, I follow evidence).
