WILL IT HAPPEN ONCE AGAIN?

While we send probes to Mars and other stars far away from where we are, searching space for another place were there might be intelligent beings just like those we're seeing every day, chances are it might be worth all the time and expense to unlock the secrets of how some planets began and ended and descended into nothingness,

The guess is there were other humanoids in the void of distant space who sought life like theirs a quadrillion miles away? Did they perish in their endeavor never to achieve success?

Is interstellar exploration going on? Will it continue when we're gone? When Earth's time has expired and all the wealth we've acquired has diminished into nothingness, when all that's left are empty plains and flesh-stripped bones, fossilized remains and evidence of of the insane dissipation of a once great civilization, will explorers be wise enough to surmise the message our demise implies?

Will they vow to not allow what happened then happen once again?
