I think you’re right about black matter, it might just be the modern day aether. The asteroid theories not so much, there is proof for the dinosaur extinction event being caused by an asteroid, and there is a measurable anomaly in the earth core which gives evidence to the moon origin theory (which was not so much an asteroid but a Mars-sized object). Also, asteroids are considered proven to excist.
ELI5: Why didn’t the asteroid also reduce life the first time or also create a second moon the second time? Why those specific outcomes for those specific asteroids?
To add onto Size/Difference, also time. When the moon was created; life wasn’t what it was say during the time of dinosaurs. Also imagine that we say dinosaurs, but thats a massive amount of time. There were numerous periods of near total extinction events, where populations and species bottlenecked. A meteor was only one of these events over our 4+billion life span as a planet.
First one was before the Solar system finished forming, no life, it was also the size of Mars. The Moon is a combination of matter from that object and matter thrown up from Earth. Second one was tiny by comparison and we actually are pretty sure we found the crater

You called?
FYI, dinosaurs are not extinct; they’re quite abundant, and we walk alongside them. For example, chickens are dinosaurs.

Because there was no life around yet the first time, and because the second time is was an actual asteroid instead of a planet.
