"What ifs" can keep you paralyzed with fear, unable to make decisions. Most people are risk adverse, in other words they are afraid of losing something more than they desire something good. That kind of thinking can keep people stuck in an unfulfilled life, afraid of the million "what Ifs". For me it was very freeing to realize that there was no real proof we were living in the last days, and no proof God existed either. It meant I could life my life in a more positive way, free of fear of judgement by God and free of fear of dying in the big A. Primitive man lived in fear of the God of Thunder, Thor, because they didn't understand weather and atmospheric phenomenon. Now we know what causes thunder, so it would be ridiculous to fear Thor, yet we are supposed to fear the God of the bible, when there isn't any more proof of his existence, other than a two thousand year old book, filled with fairy tales, contradictions and the common fears and superstitions of the times it was written.
Your questions are good, keep asking then, keep seeking answers, it takes time to come to terms with all this, but it does get easier with time.
