But why would the Ancient Egyptians focus on the 20th century?

That would be like us undergoing a huge construction project to warn people of events in the year CE 4,500. I can think of no one who has spent a moment worrying about that year!

You also missed a few events. What about the "Black Death" in the 14th century? Wouldn't 33% of the world's population from China to Ireland dying off be a significant event? Far worse than a PLANE crash?

Are you assuming tectonic plate activity is directly linked to stellar positions in the Milky Way? That makes little or no sense. The moon would have far greater impact and experts argue today whether there is any link between the moon and tectonics... with most respected ones coming down against any such link. 100 miles below the surface the pressure is 725,000 pounds psi, it's hard to believe a passing moon exerting one ten-millionth of the gravitational force of earth seriously affects earthquakes. Yet you hypothesize stellar alignments exerting 1/10 millionth that of the MOON will do so.

I am forced to conclude you have simply cherry picked normally occurring events and applied the argument of coincidence with this alignment to them. I would like to see you hypothesize proof any of your events would NOT have occurred anyway. A good place to start might be your proof "no plane crashes or tsunamis occur WITHOUT these alignments..."

I doubt your research will take long...
