understand mormons don’t believe genetics is a real science except when it is, but mormons also reject neanderthals existed?

cousin was commenting on dna being 1% neanderthal. very faithful uncle scoffed that dna science is not reliable and that neanderthals were not real and have been debunked by the church.

we tried to ask some follow ups, cave paintings are frauds and so is biology apparently, but maybe the church might want to provide some guidance on whether it embraces or rejects young earth creationism because it seems problematic that members can’t agree on the age of the earth or the theory of evolution .
