It was always testABLE, just not testED. There is a difference.

If it were not at all testABLE, (like the theory that an invisible god
may exist, since there is nothing specified to search for), then it
could never have been testED. Please try to learn the difference, and
please show how you know that an invisible god may in reality exist (if
that is what you are driving at).


Here is how the theory that "ETs (not in evidence) may exist" is being
tested using the scientific method:



Null : of, being, or relating to zero

Testing the Null Hypothesis

SETI is perhaps the most highly interdisciplinary of sciences,
encompassing not only astronomy, biology, engineering and physics, but
also psychology, metaphysics, probability, and belief. But it is, first
and foremost, a science, one to which we hope to apply the scientific
method.

[...]

The Scientific Method for the Argus search is this:

There are no ET's. (null hypothesis).

.... [W]e now design an experiment (Project Argus, for example) to try to
prove that statement wrong, recognizing that it takes only one clear,
unambiguous counter-example to reject the null hypothesis. ...
