The assault on darwinism isn't necessarily religious. Darwin essentially observed a bunch of animals, and how some are better at survival tha others, then he applied this to earth's history and theorized that all living things evolved from simple organic molecules. Scientists are finding it hard to prove the initial stage of this theory, among other things.
Well, that's very true. The religious assault on Darwinism isn't even religious; it's people wanting a deliberate personal address of themselves and their role in the universe.
I don't know if "science" will prove much of anything regarding origins for a long, long time. However, it's probable the truth is somewhere in the middle. If out of 300 possible amino acids, 256 of them combine to form either life or structures that attract the necessary ingredients of life, is it deliberate intelligent design or random natural selection? Neither and both, presuming we stop waffling about "intelligent" meaning "smart" as in having a smart thinker behind it.
Regarding likely explanations from a philosophical point of view, Platonist Monism is the only view that makes sense. In that view, you don't have a God; the universe itself is conscious. You also don't have a separate heaven, but a huge open space outside of physical/spacio-temporal reality in which things can persist and exist, albeit not by linear (time-created causal) interaction.
As Plato would say, the pattern is all, and its origin is not in the proximate cause. Personally, I like this idea just because materialism is so goddamn boring and all the proles/peasants/soul-slaves love it.
