Science tells us that everything we now know and see and touch, taste, smell, or otherwise experience all began from "nothingness", in an instant of "time". Beyond that, science is still trying to figure it out.
They call it the "Big Bang", but they have no clue what was before that...if anything. Hmmm...
Science also tells us that our universe is "alive", in that it is constantly changing; new stars constantly being "born", old ones "dying", and galaxies dancing with one another.
And we're learning that there are many other "planets that might possibly support life" out there. In my (humble) opinion our universe is "rife with life", but I can't prove it, of course.
When I think of "time", I perceive it to be simply the duration that elapses while everything we know of slowly, but surely, decays, or erodes, or decomposes, or dies, or expends itself...or however we wish to describe the process of "life", I guess. Maybe time is life itself(?).
It seems clear that time is an integral component of all existence, anyway. And as it "plays out", many and varied events occur, and we experience time's 'passage' as we measure it here in our tiny little solar system...most probably the same way other (alien) life-forms elsewhere in our Universe experience (and measure) it in their own 'solar-systems', y'know?
