In a theoretical vacuum, maybe. However we've done a fair amount of exploring ourselves and the way we work, and we haven't found a soul yet. Asserting that humans are somehow special requires explaining the lack of any supporting evidence.

This is a variant of the god-of-the-gaps argument, which is not turning out well for proponents of religion, as those gaps keep getting smaller and smaller. Again, I'll believe it when I see it.
