I'd also point out that we've nearly wiped ourselves out several times, and we're headed towards making our planet incompatible with life. If the conditions for life exist AND life evolves to be sentient AND the sentient life develops communication AND the communication fosters cooperation AND the cooperation leads to technology AND that technology allows the life to survive the vastness of space AND the technology allows for interstellar travel, all that progress could end with a meteor or a virus or a particularly strong solar storm that blows through the magnetosphere and takes our atmosphere with it.

The conditions for sentient technological species exist on earth, and humans are the only ones even close to surviving in space. Dolphins, octopodes, dinosaurs, corvids nothing else is even sharing arbitrary knowledge yet. For that to even happen, we'd probably all need to be dead.
