The Earth's rotation has been slowing ever since it formed, and a day is several hours longer now, than it was 4 billion years ago.

This is caused by tidal linkage of the Earth and the moon. The Earth turns in about 24 hours, and it takes the moon almost a month to go around in the same direction. The moon raises tides on the Earth, which place a drag on the Earth's rotation. The gravitational linkage also pulls the moon into a higher and higher orbit.

Given the general sense of your argument how do we account for the age of the moon?

I clicked back to see exactly where you felt comfortable insulting me and now find myself wishing I could meet your 18 year-old version to see if what was so obvious then to him can be quantified better now by your smugger self; how many hours longer is the earth day today and how much farther is the moon now versus then?
