Considering the fact that humans made up the concept of time, basing it off of our own planet, would it be justifiable to say that time did not exist? Given that evolution is true, there couldn't have been a concept of time at the beginning of the universe, because there were no people to create the idea of time. If you really think about it, time is something that's pretty new, considering the idea that humans, with cognitive ability, only came into existence about 100,000 years ago.
My question is, is this a valid idea, or has time just always existed? Everything we see is really what we make of it. Thus, throughout the universe, time really isn't a constant, because different planets have different days, years, etc.
But in all that I've read about theories of the beginning of the universe, they're always centered around the beginning of time. There's always an age for everything, but, maybe, could time not exist? Could it be some sort of concept that we, as humans, cannot live without, like, for many of us, God? Or is it one of those things in the universe that have to exist, like gravity? Pretty much, my question is, is this a valid idea, or am I just some rambling idiot?
