Is it real? Or is it just something that we created to explain what we can't really explain? We can't explain why we all age differently or why we all experience time differently. Or even really what time is. We are just making educated guesses as to what it could possibly be. For all we know all of this could be fake, or even just us reacting to chemicals in our atmosphere. Everyone is so focused on space that we don't even consider what's going on on our own planet. Time heals but it also isn't exactly on our side when it comes to getting what you want and worked hard for.
