Will we ever know if we're totally alone?!
Whether or not aliens exist is one of life's great unanswered questions.
Could there be an undiscovered life form on a planet far far away? Is there another human race that we don't know about - who have maybe already invented flying cars?
We've always looked to space to try and answer these questions, aiming to investigate whether the surface of a planet is fit for human (or alien) habitation.
But a new theory suggests that, try as we might, we may never discover such things, because aliens are probably living at the bottom of a frozen ocean in a distant world.

Ex-NASA scientist Alex Stern, who is behind this new idea, stated that: "The great majority of worlds with biology and civilizations are water ocean worlds."
Right, so chances are that any other life form out there has probably adapted to suit an under-water environment - makes sense (we think).
If you're unclear of what 'water ocean worlds' are exactly, Stern explains them as: "Worlds [that] are naturally cut off from communication by their interior nature below a thick roof of ice or rock and ice, [and] therefore do not easily reveal themselves."
He explains that such a hidden environment would also protect them from asteroids or radiation - you know, the kind of things that might prove problematic living in outer space.
It all sounds fairly plausible, as far as alien theories go. Although this surely means that any claimed 'UFO sightings' are definitely not the real deal...right?!
If aliens DO exist, it's likely that they're probably more fish-like than we envisioned, and definitely don't have any sort of a tan!
We will just carry on with our earth-based lives, and wait patiently for any future scientific discoveries to support such theories.
