The problem is humans only think they know all kinds of stuff, like they claim there lots of nothing out in space, but there is no such things as nothing, everything is some thing such as matter and anti-matter.
If one thinks everything come from nothing, then they don't know what it was and just call it nothing, there was some thing before that changed some how into what we know.
And what we know may not be what is real, how can we begain to under stand some thing we don't know anything about, or that it's even there like black space has some thing there.
We can not under stand what it is, but we do under stand it's displacing known matter, do we really know what black holes are no we do not. We only think we know what they are, but how can we know, if we don't know why there are so many of them out in space.
We only think as a human and humans don't know all that much, about what is out there in space, we see a very small part of outer space. And think we under stand all of it because of that, but we may know very little, matter as we know it is from what we see and under stand.
The bottom line is we know very little, but we think we know a lot but it's just not true, space and time and matter may change in ways, we can't even begain to think of because of our, very limited under standing.
like what do humans do after they use up all the earth resourses, go to other planets and take resourses as they wish, what would we find on other planets. Do we even know if life forms are on most of them or not, what would them life forms be like could we be watched by higher life forms even.
If we are what would they really think of humans, and how we are treating other humans and wildlife, and our planet that we are living on. It's simple really humans are not very far advanced, we can't even start to under stand what is real, until we under stand what we don't under stand first.
What is real humans are not all that advanced, but they think they know most things, meaning they can't keep their minds open to see what is real anymore. And when that happens very little under standing takes place, all we got is this time and space and that it.
Think about this for a min, we will die with in the next 100 years, how long after we die will anyone know most of us was even here. Just until everyone we know has died as well, that why if there is no after life. It will be as if we was never even here, at some point the earth and sun will be gone as well.
No we think we know things, but we will keep learning things that prove we did not, and after all is said and done it will not make any difference anyway. The only things that really matters, is how we add to the human chain of life, and if there is a after life for us when we die.
Some food for thought, and just my take on things.
