This is just one example that there is a lord for this world.
Another thing let's say there is no God, no resurrection, and nothing at all after death, why should I be good person?!!! when it's only one life and I'll be stupid if I waste it being ideal and lose my chance to earn and get as much as I can.
I hope you be patient with me and give yourself the chace to read the things I'm putting here. Maybe you will find something new you didn't ever know about it before.
Have a good day and wish you all the best
