I question the comment about the title text being 'sarcasm' on the basis that "we know that galaxies contain billions of stars and most of them will have planets" (I paraphrase). My view is that most of the 50,000 galaxies are likely to be very young, and we believe that the first generation of stars were large, few and short lived. | I question the comment about the title text being 'sarcasm' on the basis that "we know that galaxies contain billions of stars and most of them will have planets" (I paraphrase).

As to whether they would have had multiple planets, this is an open question. Certainly, there wouldn't have been rocky planets, as the stars will have formed from the elements formed in the original big bang, which was almost exclusively Hydrogen and Helium, with essentially no heavier elements to form anything like rocky planets. | As to whether they would have had multiple planets, this is an open question.
