Pondering

I find myself wondering why the SJ's left their calling card on Earth. If the site had been accessed by a group of vandals, it may never have benefitted mankind at all. If as in 2001 the digsite had been on the moon, it would have resolved two issues. First those who excavated it would be of sufficient technological prowess to fathom it's mysteries. Secondly, it would have been safe from both any seismic catastrophic events, or intrusion by potential (for lack of a better word) tomb robbers. Putting those questions aside I then wonder exactly what sort of vault, or chamber they will find. The sort of preservation protocols they fashioned to maintain the integrity of the contents. Like the rest of you I'm sure the film will both answer and raise even more questions. Part of what made Alien a classic film was the huge unanswered void it left as the credits rolled. I can only hope that RS adds to the franchise with even more intrigues. Just to Clarify, I know the expediton is going to Zeta Ret. I also know that they find the digsite in North Africa, or at least on a terrestrial location. I am just saying from a scientific approach as a species that wants my progeny to one day find me that I would have left the callling card, star map on Earth's satellite.
