Also keep in mind 2 points:
1. The language of the suttas had to be put in the way that the people of that period could understand. For instance, if the Buddha said that there was a Black Hole that could swallow stars or entire solar systems, then the people back then would be like "Huh???", but if saying there was some kind of Dark Monster who could swallow a whole moon, then it could get the idea across. Same things gonna happen to us, people 2,500 years from now would find our "modern" interpretations of the suttas quite strange and weird. So, make sure to keep an open mind when you encounter seemingly weird interpretations in the suttas.
2. We have to admit that the current scientific knowledge and info. although seemingly great, but is still very limited. There're still a lot that we don't know and have to make assumptions. These assumptions in turn become the constraints. For example, "humans", are we truely the only "kind" in this universe? What if there're other "humanoids" in the same Milky Way galaxy, or other galaxies, or even other universes that are subjected to different physical environments and physical laws? What if there're different universes other than this one, (multiverse?), What happened before the Big Bang, if there're many Bangs, will there be many iterations of Humans existence, possibly one per Bang? etc..The descriptions in the sutta seems weird due to the current assumptions/constraints when referencing just our own human species, under our own physical universe "as we know". The scope is still limited and the constraints are still a lot.
So the bottom line is to keep an open mind and continue to practice. THere're still a lot that we don't know but that shouldn't stop us from practicing the Dhamma..
