I know that Phaeton was destroyed with advanced technology, but I had no idea it crashed on earth, so can't help you with an opinion there.
I only know as much as a few others here but maybe I can help give some more credence on the series of events in the solar system.
1.) Earth apparently had a enormous impact with a large body 'supposedly' 4.5 billion years ago. This would have been well before any proto life had yet developed at least to our understanding. This was well before the dinosaurs and the complex organisms living here today. This was even technically long, long ago. Before even the life span of some of our Gods, which are reported to roughly be 500,000 years old or greater/lesser to that age. We are talking supremely ancient ancient history here for our solar system. This may or may not have kicked up the debris to form our moon, id wager it did not (will explain shortly) OR it was only enough to create a lesser much smaller non-spherical moon at the time. Like Mar's potato shaped moons.
2.) Billions of years later war found its way into our solar system. Probably a million years from our current date, but the exact time and date of this is largely speculative. All we know is that war began here. Not sure amongst who, or why. It could have been between the Gods of Duat and early reptilians, it could have been between other alien factions or species. I don't know. All we know is that war started up in our solar system.
3.) During this period of war several events took place around generally the same period of time. Albeit it likely with hundreds or even thousands of years apart.
3.)-a.) A large water filled world known as Phaeton was destroyed. This ejected a tremendous amount of water into our solar system that later froze into ice. After a period of time this frozen water found its way to Earth and began impacting the planet. Its unknown whither these huge glacial impacts tilted Earth off its axis, or if the earlier 4.5 billion year old impact caused this, but one of those two impacts was responsible. Earth priar to taking on Phaetons frozen glacial remnants was a rather temperate and warm planet. The abundance of added glacial ice cooled earth substantially and begin Earth's ice ages. Prior to this it is also theorized the continent of Antarctica was home to temperate temperatures and may have supported plant and animal life in greater numbers than today, this is just speculation but a possibility.
4.) At some point around this same period, most likely during or near Phaetens destruction Mars was host to an advanced intelligent species and society. I do not know their relation to us or the Gods of Duat, but it is speculated, infact I believe confirmed that there is a small population of 'Martians' living there today deep underground. This society of Martians was nuked, by extremely powerful planet scorching level nuclear devices. It leveled almost every single advanced lifeform on the world. Billions of sentient lives lost, trillions of floral and fauna gone almost abruptly.
5.) At some point to Gods of Duat arrived on Earth if they were not already heavily involved in affairs within the solar system previously due to the former mentioned affairs. They mined Gold (I believe) to help repair atmospheric conditions on Duat, and also created a gene-spliced hybrid race of themselves, us, humanity. NOT for slavishly mining gold, but to be Earth's Stewards. We were to watch over Earth, care for it and live with it. Advance ourselves, learn and grow spiritually and achieve godhead through their benevolent truths and knowledge.
5.)-a.) It is also around this time, to my understanding, the Gods gifted Earth the moon as we have it today. Either by artificial construction or they took a rocky body from our system and shaped it. Regardless it is highly speculated the Gods did this to reform the spiritual astral body connection to Earth from when Phaeton was destroyed. It is my understanding Earth's Moon is a replacement for Phaeton. This would explain its abnormally large size even though Earth does not have a sufficient enough mass to capture a spherical satellite naturally. We should only be capable of capturing smaller moons naturally like Mar's moons. Also the moons mass if complete, should have much greater gravitational forces on Earth but it does not. Suggesting the satellite may be hollow to some capacity. And third it is perfectly positioned so that it eclipses our sun, in a nearly perfect manner. By the possibilities of this occuring naturally it is almost impossible for such a perfect chain of events such as this to produce themselves on their own.
6.) Reptilians to my understanding are solely responsible for the creation of the jews at this point. Sometime after the gods returned physically to Duat they arrived and genespliced humans here with their own DNA to create the jews. They may have also wiped out several advanced cities of mankind as well to set us back, I think this is where the story of atlantis comes in. It may have been a very advanced gentile society that was destroyed.
Then humanity began to regrow, and redevelop with a parasite in its midst, slowly taking over seats of power and being assisted by their reptilian masters as well as the reptilian's slaves, the greys a formerly conquered planet and enslaved planet (exactly as they intend to do to ours.)
And here we are today.
Take heart, motivation and strength from this history however, not pessimism. Look at all we have done with our spiritual warfare in retaliation to these plans against us. Fight on. We will win Earth back, and usher in a new golden age for humanity under Almighty Father Satan and the Gods and Goddesses of Duat.
