Is exploring space worth the cost?

I don't think exploring space is worth anything it's fascinating but nothing else than this. Firstly, we'll all be dead before finding something which can be useful for us on Earth. I don't even understand why we want to leave the planet who's keeping us alive that's concerning. I think this will not end up by being something great cause everytime we looked for more it ended badly. I don't know if it's because rich people got bored of Earth and need entertainment from somewhere else or it's just curiosity but it's a waste of time.

And we all know when we try to reach something that larger than life all you get is death. We're looking forward something we can't comprehend and something we can't fight. And they'll be no one to save us this time. So i will say it's not worth dying it's fun for now new planets, new galaxies, new stars, new phenomena a lot of things to discover but it's not necessary it's called being crazy.
