It’s time for some good, old-fashioned speculation. What would happen if aliens visited earth? Now, the speculation and assumptions we’re about to make are based on logic, philosophy, educated guesses, probabilities, nature, and of course, our own history.

So, we have to imagine the most plausible scenarios, as well as try to think outside the box as much as possible.
