I think there is a good chance we are the only intelligent life in the galaxy, and maybe the whole super cluster. https://youtu.be/QfuK8la0y6s

What I like about these arguments is that they are so universal in it's debunking of extraterrestrial intelligence. In fact, it was realizing these arguments applied to God (in a much more general sense, being that powerful entities are by definition easy to observe) ultimately lead to me becoming an atheist. I would love to hear other's thoughts on them.
