Summary
This season travels the universe across an expanse of tens of thousands of years to the present day as we investigate the possibilities and probabilities of life beyond Earth. We look at the unexplainable, enormous man-made caves, structures, crop circles containing encrypted messages, and complex mathematical and astronomical equations perplexing our leading scientists. Experts have found thousands of strange drawings of beings with blue skin, multi-limbed humanoids, and more.
