Allow me to present a conspiracy...

Half-Life 2 confirmed.

Actually the sun is not light itself, but rather a massive mass of matter slowly burning at an immense temporature. So the sun is more in line with fire than light. Light is merely a byproduct. For your conspiracy to work light would have to be main thing, not a secondary. Also if the sun itself eventually lead to the illuminati than that everything that has to do with the sun would too. Such as plants, solar panels, mirrors as they reflect light and illumination to provide sight of ones self, and sight it self would be to do with the illuminati. If either the sun, or light lead to the illuminati than almost half of the things you do everyday would also do so as they too revolve around those things.

Ohhhhhh I love conspiracies ;)
