Did you fall backward above large rocks from a height of about 20 feet? I did. No harm, no bruises, just the superficial cut from the rain gutter that barely bleed at all, woke up even before the ladder fell down beside me. Twilight zone.
That didn't make me stop being partly still agnostic often though. One hour I'd think God could exist, but another hour I'd wonder if instead it was incredible luck.
Getting it as 100% certainty that God exists would only come years later, after prayer after prayer was answered, often in impossible seeming ways. I never prayed except in moments when I knew in my heart I was praying to God. Instead, that fall and rescue from the roof made me begin to actively seek to find out more about God.
Another remarkable prayer was for a foot problem in my left foot that hurt about a year and a half, until finally I prayed for it to be healed, once, before falling asleep. The next day the pain was gone. It has stayed healed. That was over 2 years ago. The other foot, my right foot, had a much less serious but similar pain, but only occasional, so I did not pray for that right foot, because it had not hurt for days, even while the left foot got worse than ever (provoking me to finally pray). Now, over 2 years of no pain in the left foot, but occasional continuing pain in the right foot, it's as clear as day that the prayer is the difference, because if it was just lucky natural healing, the right foot should have.
See? I'm not naive. Many of these answered prayers are seemingly impossible things. It's just exactly like I bought 30 lottery tickets, and one paid $500, and another paid $10,000, and one paid $100,000, and some paid $50, and some $5, and several paid $100 or $200, but every ticket paid, and not even one failed to win. It's just exactly like that.
