I thought I'd "expand" on the time-shift theory I'm proposing.
Given that as a wave expands, its frequency decreases, resulting in a longer wavelength, perhaps time is similar in its properties. If the earliest moments in time are farther away and if those moments are traveling nearer to the Big Bang's wavefront, then those moments in time may have expanded to the point of being at a longer time wavelength than the here and now that is more compressed.
If space/time is being warped by some force, then it is possible that a ripple is created when the warp rebounds back to normal space/time. This may create conditions (like Moiré patterns) where two nearby time frequencies can overlap for a short duration and manifest these creatures and anything else from the past or future, like dinosaurs, aliens, and UFOs.
