How
Space affects us because that is where all the universes and planets are. If there was no space we wouldn't be alive right now. Earth and all of the other planets wouldn't Be there. Most importantly we wouldn't have Earth or the sun. there would be no one alive because there is no space. That will most likely not happen in the future, but space is very important. some people don't realize how important space actually is. We are lucky that space is here because we would not be alive without it.
