Possible plot for sequel

Interesting idea, somehow it makes sense of why the Trilobite is called a trilobite and the word has connections to a creature from our ancient oceans that we evolved from. I think the Engineers may even initiate a massive flood to clean up most of the bio-weapon. Floods that were once intended to wipe out the fire after they tested it on ancient man. This would tie in nicely with all the mythologies at play and potentially solve how they could clean up, or wash away any surviving creatures. Perhaps some of the flood myths and ancient accounts of monstrous plagues released on the earth (similar to the Pandora myth) will tie into this all, and maybe even ancient Earth will be revealed to have been tested on and harvested... The word Paradise brings up ideas about heaven when applied to myths, but it also strongly suggests ideas about the Garden of Eden, mythological golden ages, and even Atlantis. However, the Engineers are only the servants and wished to lead us into a rebellion against the true gods. So they lead us to the stars, but eventually they decide we're to be used in any way possible in their war against the Elders. Myths about giants and monsters are a common theme in many of the cultures referenced in the film. In the Sumerian stuff Enki was a creator/ genetic manipulator, but his brother deals with cleaning up the monstrosities and ruling the Oceans-- a possible link to Atlantis in comparative mythology . Another common theme many of these cultures and the judeo-Christian stuff share on top of monsters, giants and hierarchies of gods/angels who occasionally war-- is actually the flood myth.. What if the true gods are vengeful gods and David is misleading us about the Engineers true intents? The Elders are like Zeus, and the Judeo-christian idea of god. They cause monsters to come down and punish humans, and then they clean up the monsters and giants with a massive flood. Zeus does both, but the God in the bible does it mainly to clean up the Nephillim, giants, and monsters that are stated in the bible to have been around on the Earth in the days of the flood. Saving the genetic lines of some of the humans and harvesting them. Those who survived the plague and were saved from the bio-weapon cleansing destruction that followed were harvested. I think that's how they clean up the fire and how it all ties to mythology and possibly Atlantis, plus the semi-aquatic look of the Deacon/trilobite. Shaw and David are actually going to one Paradise kingdom that belonged to an ancient Empire. A heaven/haven in the stars where they can find a little out about what has been transpiring between the Elders and Engineers and meet some peaceful Engineers David befriends ala Lawrence of Arabia. Although, as Ridley said Paradise can't be what we're expecting. It could be a Haven, but it's also seen the terrors of war. The Engineers' now destroyed kingdom on Earth is like Atlantis/The Garden of Eden. A Paradise on Earth. Or heaven on Earth. The extent of our early cultural interaction with the Engineers is far greater than we're thinking if they left us their language in a way. Their ancient island Kingdoms on Earth vanished after the Elders forced a massive flood upon them when they were rebelling against the Elders wishes. At some point the fire may have become unable to be extinguished... and the Engineers ended up with a more weaponized version of the fire. Making Weyland's extinguishing of the fire with the match trick very important. The hammerpede that's able to regrow its head is important to the King/Kingdom themes, Garden of Eden/serpent themes, and David in general because he's an immortal head of of a different type that ends up decapitated from the body of the company/kingdom.
