I have some questions about Christianity. I do consider myself a Christian I love Jesus but I’m just not the most educated (sorry if these are dumb questions)

1.will the rapture happen before or after the 7 trumpets 2.from what I know Jesus didn’t start spreading his religion, gaining followers, performing miracles ext until he was 30 years old. Why wouldn’t he start earlier? Is there a reason? 3.whats up with dinosaurs lol 4.Again I am a Christian just not the most educated. So if I have a friend that considers himself an atheist then the rapture begins and he isn’t taken up but after the rapture he decides “hm I’m gonna believe in Jesus now” is he cooked or is there still a chance for him?

Thanks to anyone who awnsers my questions if anyone does. Sorry if they seem stupid I was just curious lol
