Blaming it on aliens? Are you, perchance, in on the conspiracy to cover up time travel?
Time travel! HAH! You must be one of those covering up for the interdimensional travelers.
I have concluded that in order to time travel, you must have a space ship because the earth is constantly moving around the sun at the rate of 1.6 million miles per day and the sun is moving also. So unless your time machine is capable of spatial travel as well, you’ll end up millions of miles away from earth.
