Harry, having just watched the video I am struck by the similarity of the drawings made by the children to drawings made by others around the world. The eyes and head/face shape I quite similar. How to account for such similarity is quite another issue.
The earth is in the sun's habitable zone, has enough mass to retain an atmosphere, and has a moon large enough to stabilize its orbit. The earth has had sentient life that has had the capability to communicate with other planet since the the invention of the radio. SETI has been searching for signals of civilizations at least as advanced as our most technologically advanced nations for years now and has yet to detect a signal that cannot be explained by natural phenomena.
That said, our reach is very limited; to double digit years, and the universe is so vast that it is considered inevitable that life must have evolved somewhere else in the universe. One problem we might have is recognizing alien life. Our most "advanced" life is absolutely dependent on oxygen and shares many properties with all life on earth. (I am resisting writing a book on this subject here; I used to be allowed to teach a seminar course on origins of life and exobiology (astrobiology). The only reason I am not a member of the International Society for the Study of Origins of Life is that I need recommendations from members on two continents other than North America). It seems to me there must be life elsewhere, but probably not in this solar systems, but we might be Martians. Claims of life on Mars are now dependent on one meteorite with nodules about the size and shape of bacteria. Recent findings of water near the surface of Mars are certainly intriguing, but given the Martian atmosphere it is highly unlikely there would now be life on the surface; it would have to be below the surface to avoid the UV and X-Ray radiation from the sun. That radiation would blast apart any of the molecules needed for life as we know it. There is ample precedent for life below the surface on Earth. My official area of interest is on some of the life forms that are found below the surface. What we now now is much greater that what we knew a few years ago, and we will know much more in the coming years.

"Teach your children what we have taught ours, that the earth is our mother. Whatever befalls the earth befalls the sons of the earth. The earth does not belong to man; man belongs to the earth. Man did not weave the web of life; he is merely a strand in it. We do not inherit the earth from our ancestors; we borrow it from our children."
