I said it, and being the smart young man I am it's probably true. How long has Earth been here? How long have Humans been here? A fraction, it is well within logic that we're not the only race to have inhabited this planet.
an advanced alien race would have left relics had they stayed for an extended period of time...
Out of the trillions of planets out there, im sure at least one has to have evolved life, but the amount of time, energy, and money required to travel the immense distances between habitable planets is pretty discouraging.
If you actually look at human evolution and the formation of the universe, it really is only relatively recently (in terms of the age of the universe) that any carbon based life could have come about. It requires the universe to expand, cool, form stars, a star to go supernova, the remenants of the star to reform into another star and solar system, the solar system to stabalise and cool, evolution from single cell to highly advanced trillions of cells being.
There is absolutely no chance that there was a carbon based life form on our planet bafore us. The speed of light pretty well stops any communication let alone visitation from any life from outside our fairly immedate (in terms of the universe) surroundings. Non carbon based life is possible but hard to predict anything sensible about. From our undertstanding silicon is a possible basis for life, but you'd expect silicon based life to come about probably much later in the life of theuniverse than carbon based life due to it taking longer to form.
