I've had a long discussion with two friends about the resurrection as the proof for Christianity,
I've gotten some objections I am not sure how to answer:
Firstly, a "spiritual but not religious" friend of mine said Jesus could've been a man who simply transcended spiritually and learned how to defeat death, then he did so to trick people in order to attain worship for himself
Secondly, from an agnostic, the resurrection of Jesus could be explained by natural causes we haven't yet discovered, like a unique biological anomaly, an error inside of a simulation or a law of physics not yet discovered
I'd much appreciate any help with these objections as I found myself stuck, thank you!
