Hehe! That comment is ridiculous on it's face. The ultimate aim should be the understanding of the universe, not a bid to usurp God.
These people are delusional. They think they can defeat death? It's already been done 2000 years ago, but they don't want to hear about that....
It all goes back to pride, and the desire for self-elevation. " I will be like the Most High". It's an old story.
