The Long Āgama Sūtra 30.9

30.9

諸比丘白佛言：「我等於食後集法講堂議言：『諸賢！未曾有也，今是天地何由而敗？何由而成？眾生所居國土云何？』我等集堂議如是事。」

The monks said to the Buddha, “We gathered here in the meeting hall after our meal and discussed this: ‘Gentlemen, it’s amazing! What causes the destruction of heaven and earth? What causes their formation? What countries do sentient beings live in?’ This was what we were discussing after gathering here in the hall.”
