1 - Given that we are only 14B years into a many-trillion-year stretch, our existence now is so unlikely that it's possible that we actually are the first. Something has to be first.
2 - Aliens are everywhere, but we cannot perceive them for reasons we would find disturbing. Largely, for the same sort of reasons that cave fish cannot see light or that most species are apparently unaware of humans in their environment. Essentially, that there is no evolutionary reason for humans to perceive them.
As for grabby aliens... meh. I don't find it convincing as a resolution. It contains too many unexamined assumptions, quite like the simulation theory.
