In such a scenario, scientists expect that about a fifth of the Moon's material would have come from Earth and the rest from the impacting body. The Moon, our planet's constant companion for some 4.5 billion years, may have been forged by a rash of smaller bodies smashing into an embryonic Earth, researchers have revealed. A bombardment birth would explain a major inconsistency in the prevailing hypothesis that the Moon splintered off in a single, giant impact between Earth and a Mars-sized celestial body. In such a scenario, scientists expect that about a fifth of the Moon's material would have come from Earth and the rest from the impacting body. Multiple hits would have excavated more Earth material than a single one, which means the moonlets would more closely resemble our planet's composition, said the study authors. Yet, the makeup of the Earth and the Moon are near identical -- an improbability that has long perplexed backers of the single-impact hypothesis... Every collision would have formed a disk of debris around the proto-Earth which would, in turn, clump together to form a 'moonlet', they found. Around 20 moonlets would eventually coalesce to form the Moon.

The moon formed inside a hot cosmic doughnut, scientists say

Nonsense.
Yep!
“Researchers have revealed...” UH-HUH. Like they know. It’s just publish or perish. Any wild theory will do.
Well, that’s a relief.
“Hot cosmic donut”...mmmmmm! With jelly inside?
so that’s why the moon is all green cheese
Thank you. These people can't even tell us what they had for breakfast, yet they know what happened eons upon eons ago.
We didn’t have oceans then, but we have them now. I often wonder how all the water got here, and is it still coming? Is that why the sea level is rising?
You were there?
Interesting post SunkenCiv. Thanks.
The fact is, we really don’t know for sure how the moon formed. Another mystery is how so much water ended up on earth.
Bull stuffing.
Yep. Five billion years ago. How did they arrive at that figure? No one knows. The human genome has, so far as is known, over three billion base pair nucleotides, yet humans have only been around for a few million years. How does that happen? There were certainly a tremendous amount of positive random mutations in that time frame. Evolution is simply a theory to delimit a Creator from the argument, to obviate the need for a Creator. As a “theory,” evolution cannot be proven, as it cannot be tested in an experimental setting so it is essentially useless. Evolutionists have a lot of faith, something they belittle Christians of.
Were you?
There were oceans within the first 100 million years, but the salinity is somewhat new. :^)
