Aliens? **spoiler?**

Rating: Null/10 (14 December 2010)

I for one believe these so called Aliens are in fact Not totally aliens but humans from thousands of generations in the future. Notice the body when they become light creatures. A "brain" is even visible. They do not speak simply because they use telepathy to communicate! The aliens would simply be coming back in time to secure their own future by taking humans off what would be a fireball planet earth.
Does anyone who knows human history and our very limited space travel means actually want to save people from THIS wretched planet? Has to be future ancestors who were not capable of stopping the Sun from cooking our planet.
