The Bible is God's truth revealed to man.. Does that mean that every world is 100% literal? Of course not. In revelations they spean of the 12 time 12,000... this is not a literal number of 144,000... it is the symbolic representation of the 12 tribes of Israel multiplying in abundance.
If you truly have great theological questions, go study it. With nearly 2,000 years of history, and some of the brightest minds of their ages, I highly doubt any question you have has not been asked and answered before.
