Second, lightspeed slowing down over the last thousand years would have SEVERE consequences.

And on top of that, it would be easily detectable. Measurements of the speed of light a few years apart with modern instruments (which can measure the speed *very* precisely) would show measurable changes in the speed, if it were "decaying" as rapidly as some creationists assert. No such change has been detected -- the natural speed of light appears rock-steady by all tests.

Actually, the "theory" as they present it has lightspeed leveling off to a fixed rate in 1965, when subsequent measurements stopped varying. Very convenient.

As for lightspeed's inital speed: "almost infinity". Very precise measurements these creationists use.
