The speed of light has been shown to be slowing down based on????????

All measurement data sense the measurements have been recorded.
Even if you go by the changing measurements, c has changed by what 3k per second over the past 300 years.ÂÂ

That (I believe) is an incorrect assessment. But even if it were correct, what would the change be over a million years? A bit of a sticky wicket isn’t it mate. Anyway, like I said, your assumption is that it wouldn't make much of a difference? Hmmmmm.
Here’s a few links:

I don’t believe in a deceptive God either. Man is just too inept or self absorbed (at times) to accept the truth.
The speed of light has been measured
163 times by
16 different methods over the past
300 years. However, Australian physicist Barry Setterfield and mathematician Trevor Norman, reexamining the known experimental measurements to date, have suggested a highly controversial discovery:
The speed of light appears to have been slowing down!
Canadian mathematician, Alan Montgomery, has reported a computer analysis supporting the Setterfield and Norman results. His model indicates that the decay of velocity of light closely follows a cosecant-squared curve, and has been asymptotic since 1958. If he is correct, the speed of light was 10-30% faster in the time of Christ; twice as fast in the days of Solomon; four times as fast in the days of Abraham, and perhaps more than 10 million times faster prior to 3000 B.C.
