"Our" universe does not have the "right parameters". There are no "right parameters". You are thinking far too narrow. I suppose the parameters are right for stars to form between 1E32 and 1E35 grams. I suppose the parameters are right for galaxies that form into spirals or blobs with between 1E6 and 1E13 stars. I suppose the parameters are right for life that exists at 290K and a g of 10 N/kg.
But who is to say that with different parameters, everything would be the same, just "phase" shifted? The life argument is particularily narrow because those parameters could be different within our stellar neighbourhood, let alone the whole universe. Who is to say that there is no (intelligent) life out there that exists at 200K with a g value of 80 N/kg? Why do we think we are so special? Why are we so conceited? Because of religion, that is why.
Centre of the solar system, centre of the galaxy, centre of the universe, and the only intelligent life form.
It boggles my mind to think that there are some people who still believe all these myths.
As for the causation problem, it is a problem for both sides of the coin. Bible thumpers argue we couldn't have come out of nothing and that there must have been an original designer. The free thinkers then retort that if somebody designed it all, who designed the designer?
So really, arguing over original causation is an exercise in futility.

You misunderstand me here. I'm not saying that our universe is a unique snowflake of improbability that proves a Creator.
I'm saying that in our universe, if the charge on an electron was different, or if the spin of a top quark was different then things would be very different; there might not be enough black holes to form galaxies or particles might be too massive to allow supernovae or stars might not form at all. No stars, no heavy elements, no life. And that's fine, because in another universe the parameters would be right and things would take place there rather than here.
"Our" universe has the right parameters for our universe's existence.
So if there are finite or infinite parallel universes then there will be others that have all kinds of conditions that are condusive to some sort of life, similar or completely different than our own. There will also be universes where nothing ever forms, universes that last only billionths of a second, and universes that die an early heat death.
What I meant is if this was the case, then the fact that we can observe the universe and think these thoughts isn't special at all.
That's one facet of M-theory; universes are created by collisions between membranes in 11 dimensional space and each universe can have completely different laws of physics.
Other interpretations of quantum mechanics have parallel universes that all have the same physical laws but exist in a state of quantum superposition, they effect each other (one way to explain dark matter) but are seperate.
EDIT: Lol, I was wondering how long it would take to see a reference to the Flying Spaghetti Monster...
