That's not absurd, it's a perfectly plausible philosophical hypothesis. The only thing that's wrong with it, besides the fact that the "first conscious entity" sounds awfully similar to a god, is that I have no idea how to test your hypothesis scientifically. But that shouldn't be a problem if you don't intend your hypothesis to be a matter of science in the first place.

By the way, "consciousness is a requirement for a universe to exist. Without consciousness the universe exists as random information..." is self-contradictory, since existing as random information still counts as existing. I don't think this is what you intended, so I would suggest that you change it to something like "consciousness is a requirement for there to be order in the universe" or something along those lines. (Caution: if you say "consciousness is a requirement for the universe to be intelligible", that becomes sort of tautological.)

Anyway, happy philosophizing!
