Theists, how did you decide which god/gods/goddess/goddesses to call The One/s?

Time for a Sunday Question.

A family member posted this image on her Facebook Wall. Seeing it made me wonder how various flavors of theists come to accept the particular deity they worship, while rejecting all others. Over the course of recorded human history, people in various separate locations have worshiped at least 3,000 different creator deities; each one claiming to be the one true creator (or in a few cases creators, where a male and female deity give birth to the Universe). In the 200,000 years before we learned to write and make glyphs, there must have been many more creator deities proposed but now long forgotten in the fog of deep time.

In each creation story, the deity or deities involved claim they are the One True Creator/s; and that all other claimants to creation are lies invented by some evil adversary or ill-intentioned men to turn mankind away from the One True Way. It’s pretty clear that—since each claims to be the Only True One/s—all those claims cannot possibly be true. Either 1 is true and 2,999 are false, or 3,000 are false. And so even the most vehement apologists for a given faith is an atheist in regard to some 2,999 other faiths. Agnostics and atheists just take it one god further.

Granted the actual number of creator gods and/or goddesses is hard to count. Godchecker lists a very large collection to get you started if you care to make your own estimate. But the point stands even if the actual number is 50% higher or 50% lower. 3,000 is a nice round number with a real list of names to support it, so it will do for purposes of this discussion. I’m wondering just what the whimsical “How to become an atheist in 3 easy steps” graphic implies. Why would a theist look at such a large plethora of gods and reject all but one of Allah; Amun; Apollo; Arinna; Atum; Atun; Borr; Brahman; Coatlicue; Ea; El; Elohim; Enki; Esege Malan; Eurynome; Father, Son and Holy Spirit; Freyr; Gaia; Garuda; Helios; Hepa; Huitzilopochtli; Hvar Khshaita; Inti; Inuit Raven; Ipmil or Radien-Attje; Izanagi and Izanami-no-Mikoto; Kamuy; Liza; Lugh; Marduk; Mbombo; Mithras; Nanabozho; Ogdoad; Ojibway; Ptah; Ptah; Ra; Ranginui and Papatuanuku; Rod; Shemesh/ShepeshF; Sol; Sol Invictus; Surya; Tonatiuh; Unkulunkulu; Utu; Viracocha; Vishvakarman; Yahweh; and of course, Zeus—to name just a few? If I left yours out, it was an oversight. Feel free to post the name of your selected One/s. Anyone wanting a far more complete list of deities to evaluate for likelihood of being The One/s can find a mother load at Godfinder.

So my question for theists is, what about the other 2,999 claims led you to be atheistic toward the deity of that claim, and how does that same standard not apply your selected One/s? Atheists and agnostics feel free to chime in on why you find all 3,000 claims unconvincing; but please keep the discourse respectful. It’s fine to debate the validity of the evidence for the truth of a claimed deity. It is not okay to debate the character and intelligence of another Fluther member, and doing so will be flagged.
