Are we alone in the Universe?

[g-boy]

There is too much to say and there is too much we don't know to get into the matter/antimatter-always-existed-big-bang-theory discussion. I will say this, there is virtually no doubt that there is intelligent life elsewhere in the univserse and in our galaxy. The universe we do not even know the size of, and from what we can see there are an immense amount of galaxies. Within our own galaxy there are trillions of stars. All it takes is a planet orbiting a star, with the elements necessary for life. This is for life as WE know it, there is possibility of life without being carbon-based and existing in the same conditions as we do. Besides, we know life can exist at the bottom of our oceans in tremendous heat and what once was thought of as toxic chemicals, and they actually thrive on it. These extremophiles do exist, and there are even some fungal spores that can be outside of our atmosphere, return to Earth, and grow. There is a good chance that life exists in a massive ocean on Europa, and that it possibly once existed on Mars. If it is not limited to Earth in our solar system, and not limited to room temperature climates with plenty of oxygen, sunlight, and/or food, then one must imagine that life (and therefore intelligent life) is a common occurrance in this and other galaxies.
