The opening of this shiur, in Rabbi David Yosef’s own words — taken from the captions, so names and Hebrew terms may be approximate.

Monday afternoon national shear. Welcome everyone. We're continuing the subject the amazing topic of UFOs, extraterrestrial beings, and space travel. Contemporary halakhic analysis. Uh this is a very interesting topic, very contemporary topic. Actually, this past week the government started a new site. It's called alien aliens among you. And they wanted people to think that there are extraterrestrial beings, but they're not referring to that. They're referring to illegal aliens. So, I just want to clarify. This topic is we're not referring to illegal aliens. These are legal aliens, but not wanted aliens. We're talking about extraterrestrial life, life from on other planets. Last week we saw two conflicting opinions. We saw on the one hand the opinion um of the commentary on the Sefer Yetzirah from Rabbi Judah Barceloni, who definitely acknowledge the possibility of life on other planets, intelligent life on other planets. And he even seems to have acknowledged that maybe it's possible that there is a Torah out there. On the other hand, we have the opinion of Hasdai Crescas. And he says um that in his opinion he does not accept the possibility of life on other planets. So, we saw these two conflicting views. Um I I'm sorry. Rabbi Hasdai Crescas [clears throat] also, in his opinion, he said there's nothing in according to a Jewish theology that precludes the possibility of life on other worlds. So, we have the opinion of Hasdai Crescas, the opinion and the very first opinion
