We’re assuming that alien life requires the same things we do, why?

We think that life has to be really complicated stuff all mixed together. So that means that whatever a new system of life is like we think it will have to be stuff that can be in a bunch of different shapes and still be able to mix together.

So far the stuff on earth that makes up life is really good for this. All of our stuff is like LEGO bricks and it’s shapes can do a lot of cool things really easily and all the water we have is like the lego base that helps all the bricks come together and make really cool stuff.

It’s possible that there is really cool stuff that doesn’t work like lego but can still do complicated stuff, but right now it’s much easier to search for lego stuff in space so we’re trying to find out what planets might have cool new lego bricks on it.
