Aliens don’t exist. Abiogenesis required an unfathomable unlikely event to occur and it only happened once in the history of our Universe

you can't mathematically say that. We have singular event - earth. We don't know if it is (on average) one to 100 solar systems chance (would've been big). One to galactic. One to cluster. One to cluster of clusters. One to entire universe. Or one to 10 universes and we're 10% fluke.

The Miller Urey experiment showed that the steps that occur just before abiogenesis are pretty common and easy to make

Yeah, based on nothing. Cool story bro

Oh yeah, and a lot of preexisting conditions were met for me to fuck your mom, but she still won't return my phone calls

The Miller experiment showed that amino acids can easily form in a reducing atmosphere with lightning strikes. It never proved that they could spontaneous organize into a self replicating molecule. Doesn’t prove shit. Also nobody can even begin to explain how chirality arose, considering practically every amino acid on earth has the same handedness

If life is so common then why does all life on earth seemingly arise from the same microbial ancestor. Even viruses use a nearly identical mechanism of passing on genes as we do, just trivial differences. Seems pretty rare to me

You are proof that life existing in this universe is a non-zero chance. The end

The seed reactions of abiogenesis could occur quite often, but they would be overwhelmingly out-competed by already existing life. Just about every cubic millimeter of the Earth's surface and oceans (except for very hostile environments) is loaded with microbes looking to exploit all sorts of chemicals as food. Even the LUCA and many of its ancestors would have been very hardy compared to the likely delicate reactions of abiogenesis, and would have spread out throughout the oceans early on.

With that logic, why do we have so much biodiversity and species overlapping the same food supply/ecosystem? Shouldn’t there be just a few plants, a few animals, and a few microorganism that outcompetes and makes all the other species go extinct? Seems like a very hand wavy argument

Wouldn't you say that's where earth is heading? It's rather odd to think that in the couple billion years and the several massive environmental changes that evolution would just instantly create the perfect plants out the gate?
