There may be life on worlds in other solar systems.
We dont know if this is true and we cant test for it now, but we can theorise on ways to get this information.
If we cant even theorise on ways to test for something then its a good sign that it does not exist
According to whom? Did gravity not exist 3000 years ago because nobody had theorized a way to test for it? I am thinking it did.
