Alien Mystery

A glowing object descended in the forest and you saw it from your house close by. You did not bother informing anyone about it and rushed to the forest to see what the object was. After walking for a while you reached the middle of the forest and you saw there a UFO. You also noticed that there were aliens all over the place. They will not allow you to leave but being a very smart person you are surely going to start looking for a way to escape from the forest taken over the aliens. Observe the surrounding very carefully and you will spot things that you can use.
