premise: A teenage girl in a crowd of people looking up at something.
hypothesis: somebody saw something in the sky
explanation_1: People can look up at something without looking in the sky.
explanation_2: People looking up does not necessarily mean they saw something, they could be waiting to see something that isn't there yet, could have missed it, or there could be nothing to see.
explanation_3: Not everything that is looked up at need to be in the sky.
