Are there valid theories about life forms not using carbon as basis?

In: Biology

Carbon is pretty unique in how versatile it is. Almost nothing else can bond with so many things in so many ways. Plus, it’s a solid in earth temperature which is probably helpful (not sure though)

And we’ve pretty much discovered every possible element at this point, save for weird isotopes of really heavy elements that would be too rare to form life anyway.

If you consider robots a life form though, then they could be built with a lot of things

I vaguely remember reading something about the possibility of Silicon based life, have a quick Google and you’ll find articles on it.

There are some theories of silicon based life, but it is only half as versatile as carbon (or less).

Silicone based life has been found, but having an extra valance shell then carbon makes it less stable. So while possible it is not as practical.
