So science is something we use for getting us knowledge about the universe?

We could call it a tool then. Right?

Yes

And it’s better because it delivers higher quality knowledge?

It’s not “better” than other options, and it doesn’t deliver “higher quality” knowledge. It is the only way of obtaining knowledge about our universe. There’s no other option that it’s “better than”, because the other options don’t result in “lower quality” knowledge. They don’t provide any knowledge at all.
