Where did the universe come from and did a creator have a hand in making it? As scientists learn more about the universe, our ideas about exactly what God made (the earth, the universe, the multi-verse even nothing but empty space) have come into question.

What if an extra-terrestrial force attacked Earth? What might that look like and how will the people of Earth respond? Consulting a cast of world-renowned scientists, survival experts and defense experts, National Geographic explores this frightening scenario. Experts reveal what could motivate alien invaders to attack Earth, and speculate on how the attack might play out, the strategy alien invaders might use, and the most effective ways for humans to respond.
