Do you remember the Gong Show? The TV show where when someone did a deplorable job they rang the gong and then yanked them off stage? You need to listen to the gong.

Your first sentence, above, which I quoted has absolutely zero to say about sentient beings on those planets and whether they do or do not believe in a deity.

Your sample size is still 1.

Countless continued:
"Similarly, I have no first hand information about the moon landings."

You have even less information about God, Moses, Jesus Christ, George Washington, and Paris Hilton. None of whom you have personally met. Your lack of personal knowledge about diamond cutting doesn't refute the fact that diamonds are cut.

Countless plunged into the depths of despair with:
"Sammple size is irrelevant."

Gong!

And then completed his leap into obscurity with:
"What matters is the probability you obtain for or against some theory."

Gong Gong Gong. Probability without concern about sample size? Probability with a sample size of 1?
Are the following terms new to you?

AVERAGE
COEFFICIENT OF CORRELATION
CUMULATIVE DISTRIBTION
POPULATION COVARIANCE
POPULATION VARIANCE
SAMPLE COVARIANCE
SAMPLE VARIANCE
STANDARD DEVIATION
