Certainly not. Death also thought that he would always exist, but was eventually killed by Dean. So I wouldn't say that he can kill God. He has none of those overwhelming powers God has, at it's best, Death created a luner eclipse. Amara would probably kill him in the same manner she has killed Metatron.
