Why do scientists look for life on planets only similar to our own? Couldn’t there be life not based on carbon?
Well, you can't rule it out, but we've never seen non-carbon life before, so we wouldn't even know what to look for. Because we know what carbon-based life is, we know to look for things like Methane in the atmosphere, organic molecules, etc.
