Enock wants to know:
I wanted to ask what scientists think with regards to the possibility as alien civilisations somewhere in our galaxy or other galaxies, as well as the possibility of them having visited earth in the distant past? If there isn’t evidence parse, how to we explain some constructions around the world, stone hedge or the symmetry of sphinx in Egypt or any other seemingly impossible engineering marvels certainly misplaced for the supposedly primitive life of those eras?
Can you help?
