I'm liking Henry Kroll's thinking on a Lunar impact of Earth. I'm unsure of the impact size which seems a little on the small side but other than it's quite compelling.
Here's the blurb:
There are no cave paintingsof the Moon prior to 11,712 years ago. The oldest painting of the moon we can find is only 9,000 years old in China. Moon rocks date to 6-billion years--older than the Earth. One was dated 20-billion years which is billions of years older than the Big Bang theory.
If you still think the moon has been up there billions of years where are the Moon meteorites? Mainstream science has only found 13.2 pounds of lunar meteorites--about the same as Mars meteorites. Mars is a lot further from Earth, it has more gravity than the Moon and it has an atmosphere so where are the Moon meteorites. Given the fact that the Moon is covered with craters, we should be able to walk out on the desert and pick up tons of them--even build houses out of them but there aren't any. If it has been up there billions of years we sould be tripping over Moon meteorites.
There is only one object up there in the sky with enough mass to tilt Earth 23.5 degrees and that is the Moon. It bounced off the Earth exterminated all the tribes, camels, horses and mastodons in North America 11,712 years ago. I used Arizona edu/impact effect computer. I put in the mass of the moon, 7.35 E 33 kilograms, the mass of the Earth 5.98 E 24 kilograms and angel of 11 degrees and a speed of 2.5 kilometers per second. The resulting impact depressed the Earth's crust 5 kilometers. The Arctic Ocean is 5 kilometers deep north of Alaska. It took 7oo terramegatons to tilt the rotational pole of Earth 23.5 degrees.
Tilting Earth 23.5 degrees doubled arable land and doubled the productivity of the oceans because now we have more pronouced summers and winters as sunlight hits the Earth 1,800 miles further north and south thawing out the ice caps. It also doubled the productivity of the oceans releasing more free oxygen. The impact raised sea levels 300 feet. It was an engineered project designed to make Earth more productive for larger human and animal populations. It was terraforming!
