I like how your mind is working. Recently, my brother-in-law started me along a similar path of questioning.

• How do we know that this is the first end-of-world event. (The Bible mentions the great flood.)
• How many end-of-world events have there been?
  You mention that the people who have the same questions might help you but the more I ask the more nebulous it all gets.

I look forward to reading some of those answers. 👍
