I feel most science fiction cannot actually deny it's religious roots, though it has moved past them now.
Look at the major sci-Fi themes
1 Man in to space (The search for the heavens)
1a Star Wars (The war in heaven angels and demons)
2 The Aliens are coming (The 7 year tribulation, man against demons)
3 Robots/AI/ Artificial life (man playing god and creating in his own image, then losing control of it)
4 Post apocalyptic distopian future (speaks for itself)
5 Time Travel (The quest for the source and the ultimate destination)
6 Superpowers (Apotheosis and avatars)
7 Man supplanted by beasts is possibly the only exception as this a fearful scenario exclusively seen as rooting itself in evolution.
Is this perhaps the root of the "Mad scientist" trope(See below, for spot the difference)
