The characters are wearing modern clothing, and one is carrying cell phones in a Sci Fi setting. It's the reverse of D&D where the anachronism is modern stuff in an ancient setting, whereas this is modern stuff in a sci fi setting. Sure, the cloths and phones from our era could exist in the far future, but everyday people wouldn't be wearing/using them - those items would either be long forgotten, or in a museum.
so what will future lizardpeople be wearing? Maybe floral shirts are making a comeback like bellbottoms or bobby sox, and we dont know that the multiple 'cellphones' being used aren't some kind of holographic projector or drone interface
