I've come to the realization that humanity's presence won't mean anything

Look at all the great things we have. Vehicles to get us around, technology and gadgets, and all the other things man has created. And in 5 billion years from now, I know a very long time, the Sun will expand and destroy Earth. Unless man can figure out how to build starships and get around the galaxy like in the movies, humanity is screwed.

Of course there's more factors other than just the sun expanding, but if man is thinking they'll leave behind some Earthly relic for aliens to find in 10 billion years, welp, Earth and all of humanity's things left behind, will be gone by then.

Indeed.
Humans over rate themselves.

@Magenta I think we've suffered for too long with an idea that whatever happens we can solve our way out of the problem by simply throwing more science and engineering at it.

Whilst Science and Engineering undoubtedly have brought us untold benefits - and some things we all wish had better not been invented - that often misses that one of the biggest causes of many problems is human behaviour!

However, as Twiigss points out, some things are far greater than humans ever can be, and are beyond any possible human control.
