The Bible does speak about cremation. Check this link out.

OK, I stand corrected. The link says “Bodies were burned as a form of condemnation”. It should say “as an expression of condemnation”. But that does not mean burning of bodies is condemned. When I got my new drivers license, I burned the old one as an expression of condemnation of the terrible picture they took of me. I practiced my smile in advance for the new one. It’s much better.
Very few people were buried. The practice during Christ’s time was to collect the bone after decomposition and interred them in an ossuary.
