dhw: But it doesn't alter the fact that the more quintillions of planets and solar systems you have, the greater the chance of a stroke of good fortune and the more unlikely the argument that they were all needed for the purpose of producing humans. - DAVID: Now we have a multi-galaxy theory as opposition to fine-tuning. But it is not as productive as infinite multiverses to deny fine-tuning. This universe is finite! - I didn't know multi-galaxies were just a theory. When did you discover that ours was the only one? “700 quintillions” of planets is, of course, a theory, and a pretty pointless one at that. The argument here, however, is not against fine-tuning or about billions, trillions, or quintillions, but simply the fact that the more planets and solar systems there are (and bearing in mind that even if the Big Bang happened, we have no idea what preceded it), the greater the chances that one of them will hit the jackpot. This is no more mind-boggling than the theory that all the untold billions, trillions or quintillians of planets and solar systems were invented by a single mind of unknown provenance for the purpose of creating little ole you and me.
