>Also what makes life so important? Maybe with a different fine-tuning, there would be different beings with even better characteristics than "alive" and "conscious", characteristics that we can not even conceive.

Exactly. God could have created humans so we can live in empty space, he could have created other creatures that do.

>Ok, we have a universe where there is a tiny bit of life and consciousness, but was it really the aim, or is it possible that had the values been different, some other being would be saying "wow, it seems that the universe is fine-tuned for "shlubagazorp", something that we cannot understand?

Universe seems to be fine tuned for empty space and black holes to me. It seems to favor nothingness.

>Also, isn't it possible that there is more than one universe and that we just happen to be in one where life is possible, since we could only happen in one of those? Wouldn't seem very fine-tuned in that case, would it?

This is the cosmological multiverse theory.
