If and when humanity dies out how long do you think our last evidence of existence will be?
It depends on the technological sophistication of our non-human successors at their zenith assuming this hypothesis is true. When the sun uses up all of its hydrogen fuel, it will turn into a red giant and probably consume the earth. There will be no evidence of mankind after that since the earth will either be gone or burnt to a crisp if it still exists. Mars will have some rovers on it and the Voyager probes may still exist, along with other human probes but this is beyond the scope of terrestrial successors. Eventually the heat death of the universe will occur due to its unending and ever accelerating expansion and all life in the universe will cease to exist. Other universes will bubble into existence and then new questions will be asked and answered in forums including responses identical to this one.
And also don’t forget that Leave it to Beaver episodes that were broadcast in the 50s will drift out through space at light speed until the universe ends so that will also be evidence of humanities existence.
