Anyways, this discussion can be "locked" now, we've reached a consensus.

"Life, death; chicken, egg; regardless, at the end, I'll reap Him too." -Death the Pale Horseman

That quote signifies that age doesn't really matter. Even if the Leviathans really ARE older than Michael, they're nowhere near as powerful. That is all.
