I have been researching the Moon with my binoculars for a long time. I have come to the conclusion that the Earth impacted venus which hit the moon and died and so that's why dinos are dead

I'm not sure what the title has to do with the first post. Is it a serious question?

Evidence strongly suggests otherwise. Just a couple of examples:

1] Planets do not normally go careening around the Solar System. The orbits of the Venus and Earth have been stable for a long time.
2] Your hypothesis would suggest there should be monster craters on the Earth and Moon. Craters as young as the dinosaurs. There isn't. Biggest crater Chicxulub is about 100 miles across.
3] Both bodies would likely still have molten craters deep into the mantle from such a recent impact.

There are scenarios similar to what you describe (Moon was cleaved off Earth by an impact of a third body), but the timeline is billions of years, not 10's of millions.
