Yes and no. From an outsiders point of view, all those do look like versions of the same god, but there are clearly incompatibilities. About 30% believe in "God" and his son Jesus, about 25% believe in "Allah" and his true prophet Mohammad, and less than 1% don't accept ether of these two auxiliaries and believe in "G-d" as they are apparently superstitiously compelled not to include all of the letters of the word.
When you all can agree on the true nature of your deity then maybe us outsiders will be willing to attribute half the world's population to the followers of a single god. Until then your claimed perceptions of that entity are different enough that they cannot be seen as one. Have fun hashing it out, but leave the other half of the world out of your little fight. So the original response that 70% of the world doesn't believe in "God" (the Jesus one) stands.
But, since how many people believe in something doesn't have any bearing on the truth of it and that belief (in "God") is not on topic anyway, does any one want to talk about the origin of the genetic code?
