Ah yes. Velikovski (the last reference is based on Velikovski).
He's been VERY thoroughly debunked. I was quite surprised to find that a few people out there still believe in him.
Here's an easy test for folks -- find some real evidence that the Earth had a global catastrophe 3600 years ago. To make your research easier,
here's what happened (documented, historical evidence with good time correlation... no radiocarbon dating in case you wondered)
...in the years between 2900 BC and 2000 BC:
(which would be 3600 years ago with a healthy bracket on either side)
...and between 4000 BC and 3000 BC:
...and so forth back to the 10th millennium BC.
That time period covers two (and a bit) of these "Catastrophic Encounters With Horrible Planet." Perhaps you can point to the sections in the
Earth's history here that indicate Horrible Planet Showing Up And Wiping Things Out? I can't seem to find it.
