Earlier quoted context omitted.

They specify wild mammals. Humans are like 600 megatons I think.

60 megatons. Study mentions that the 12 megatons of ants are equivalent to 20% of the total human mass.

No, 600 megatons (~E12 kg) is closer. There are E10 humans and we weigh E2 kg. More precisely: 6E1 kg * 8E9 = 5.6E11

To them they are the apex predators, just like how humans think they are

I don't think they are capable of such thought. They also don't know much about the world.

They know that the Earth orbits the Sun. Source: I asked an ant about it.

About 500 megatons. 7e9 humans * 0.075 tons/human / 1e6 tons/megaton

Wow. That shows how much wildlife we've killed off. Whales, buffalo, elephants, and the list goes on. In a balanced world, I feel like we shouldn't have more mass than the total of all these massive creatures. I wonder in what year human biomass passed wild mammal biomass.

Pretty sure it's less the reduced wildlife and more the efficient food production of / for humans. Modern agriculture is crazy efficient compared to grazing, foraging and such - in forests, where the relatively "unproductive" trees get most of the light.

Numbers are to be considered about dehydrated mass, again according to the study.

20 quadrillion. That's 20 million billion. So given there are roughly 10 billion human beings on earth then the ants outnumber us by a factor of two million.

However, at 5 milligrams each the 2 million ants are only about a leg full.

But that leg must weigh more than a person because their total biomass of 12 megatons is "more than all the wild birds and mammals taken together".
