The atheist/evolutionist game is is always the same and they only have a few tricks in the book but tricks is what it is.
Their biggest trick is to conflate basic, simple procedures and treatments with something as morally repugnant as human/animal hybridization.

We AREN’T going to live forever, no matter how hard scientists try to make us or want us to think that they can accomplish it.
There is NO justification for going into this kind of territory.
