Upon falling into.. something.. you awaken on solid Earth. Everything looks.. quite different. You recognize the landscape as being your home.. but wait.. your home.. it isn't here. It's all just grass and field! The air also smells so clean and pure.. almost as if there is absolutely zero air pollution of any kind. Your lungs seem to respond happily to this! You decide to look around and notice that the birds look quite different than any bird you've seen. Same goes for any animals you see roaming the grassy fields. The sky also looks more blue, almost more 'clearer' due to no air pollution. You look around a bit more and notice some sort of tribe in the distance. The inhabitants of this tribe appear to look similar to monkeys in a way, but they are humans. They appear to be Neanderthals. But wait.. that can't be right.. we evolved from Neanderthals.. didn't we? How long ago was that..? 50,000 years ago. You start to realize that you have somehow been transported nearly 50,000 years into the past! But how is that possible?

What do you do now..?
