Yes. I am the official CEO of Dashing Your Dreams Limited, where I always ensure that no one's dreams are ever fulfilled, because mine sure weren't and I'm a bitter old man!
No, it was probably named after the star it orbits, with the C possibly meaning it is the third planet in that solar system so far as they can tell. I can't say for certain without actually examing the origins of the name.
Imagine if we travel lightyears to this planet, and when we land we see houses just like ours, with families just like ours sitting down and watching sitcoms just like ours? Kwazy.
I have noticed that when most people talk about contacting other life, they always assume the other life will be more advanced than us. There is just as much chance that they will be the underdeveloped species; then the question arises- should we or shouldn't we become their Gods?
Well, one aspect of the Many Worlds theory states that if you go to the edge of the universe you will end up in another one, one that is almost identical except with minute differences that we might not even be able to detect because they could simply be a slight variation in the radiation emitted by some white dwarf in a galaxies millions of light years from Earth.
As for the other, that's also anticipated by most scientists, and as for the gods part...let's not start acting like the Goa'uld or the Ori, please.
A twin scene would be very unlikely, but I mean humanoids like us, that evolved "along-side" us.
Chances are minimal that we would ever encounter such a species, but it is certainly possible. Of course, we do have one humanoid species evolving on our planet right now that is gaining sentience: chimpanzees.
And if we were to find a race of primitave people, I would not like to treat them in a way such as being their "god", I would simply prefer to watch in amusment.
It is doubtful we would even be able to interact with them on any real level unless they were humanoid, and even then it's possible they could look like humans but be silicon based or copper based and otherwise share such a different environment for habitability that it would be pointless.
