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 current model of lunar formation grew out of the data from the lunar missions, in particular, the isotope ratios of the lunar soil samples as compared with those of the Earth.
In more recent years, a couple of problems arose; the math shows that the composition of the formed Moon would be about half from the proto-Earth and half from the impactor. The isotope ratios are not an exact match, but none of the known isotope ratiios from the rest of the Solar System would provide the needed match.
The second problem is obscure, but is my favorite -- that the fossil nautiloids preserve the major septa, showing the lunar month length over a couple hundred million years. There was a nice slow lengthening of the month, but the Moon was far too close at the beginning of the fossil sequence to permit an impact origin of the Moon -- the Moon has to have been formed elsewhere and captured. Since there's no way around the fossil evidence, the non-exact / pretty close match of the isotope ratios loses significance quickly.
Captured? I wonder where it came from.

Does that give you a proportional perspective?
You’re extensive and well supported criticism is very convincing.
Sheesh, I have come to believe that modern scientists are not they're all cracked up to be. I question so much that "scientists" theorize. Funny how Copernicus and Newton and others were correct in their theories. Every time I watch Sheldon as a theoretical physicist with his white board on "Big Bang", I chuckle. Hey, how about that Haldron collider that didn't prove squat?
In other words, speculating “scientists” still don’t know.
Basicaly that is all todays science is reduced to, as it can easily reverse itself given enough time and new findings.
Thank you for those links, interesting stuff.
I thought the Moon was Cheese.
I’m wondering what the basis is for your labeling a new theory “nonsense”. You must have some basis for your statement. Obviously you weren’t there eons ago.
So what is the basis for your statement? Alternative theories, research, data?
Read my post again, then get back to me.
Read the first six chapters of Genesis. That will answer a lot of your questions.
Thanks for clearing that up. Wish we would stop wasting all that money on basic science, technology, advanced research, space exploration, etc. All the answers are already in a book.

Your intent was what? Try again.
So, this was sometime within the past 6000 years?
I blame global warming.
