You should educate yourself.   Nothing recognizably human existed until 3 million years ago.    Each of the major natural global extinction events in earth’s history that came before the current anthropogenic one predate our existence by tens to hundreds of millions of years, and eliminated a higher percentage of species in the biosphere than the most dire projections of the current anthropogenic extinction event.

The animals that survive each global extinction tend to be those with the broad geographic distribution and able to adapt to wide range of environments and subsist on wide range of food sources.   If the extinction event is sudden, ability to go underground helps.  We check all the boxes for traits required of extinction event survivors.  That was not the case with the great auk, the dodo, or the passenger pigeons.   They each checked boxes for species particularly vulnerable to habitats loss or predation. 

I think any extinction event which will wipe us out, as opposed to killing large numbers but leaving numerous viable population of survivors, will likely have to be severe enough to make essentially all the land on earth uninhabitable by any animals larger than a large rat, and prevent all planting and harvesting, or foraging, for several continuous years at least.

You should pay attention to what other people post. I was talking about three specific species, each of which went extinct since the 17th century.

Your obfuscating about global extinction events is both off point and a clumsy attempt to cover up a demonstrably wrong statement.

I suppose we could wipe ourselves out the picture I just think us going back into another dark ages would be more lightly.
something that intrigued me about the big space program by jim alklele was that most of the goldilocks solar systems in the goldilocks zone of the galaxy are around 1 billion years older than ours. This might mean we are a bit like infants surrounded by wise old men so to speak. If they are out their they might have a lot to teach us and It also might mean less waring planetary youngsters in the region and more evolved life. pure speculation much like the debate on if we will annihilate ourselves something we may not know for sure until it's too late.
