Does cremation destroy the soul? If someone's body is cremated, how can they be resurrected?

No. The soul is released from the body when the body dies. At some point, the soul may manifest into another form through reincarnation. There is no resurrection because there is no death.

I see no reason to believe such a thing.

it won't. their soul comes back to our Heavenly Father....either with Christ or be Judged by their sins

No, your energy has already left

No. You’re dead. It doesn’t matter if they burn you, bury you or stuff yiu and use your body to frighten tourists.

You’re dead.

Your spirit's already left, that's what resurrected
