From the Royal Society (the national academy of science in the UK) and NASA, to the European Space Agency, the UN office for Outer Space Affairs, and to the Vatican's progressive astronomers, excited discussions abound, all centered upon the existence of highly evolved Space Brothers (aliens) and their anticipated arrival here on earth. Lord Martin Rees, President of the Royal Society announced that aliens may be "staring us in the face" in a form unrecognizable to humans. (Official Disclosure: Prepare for Contact, Donna Anderson, http://www.officialdisclosure.com/) Not everyone is excited by the "anticipated arrival" on earth of the Space Brothers. Steven Hawking is not. He has issued rather dire warnings against making contact. Nor by all indications is Ridley Scott enthusiastic.
Scotts' "Prometheus" is based on evolutionary thinking and the Myth of the Extraterrestrial, hence the Engineers (extraterrstrials) are shown in the first scene seeding earth with the primordial ingredients for the evolution of mankind.
Weyland is one of the Engineers evolved products. Weyland is sterile and yearns for immortality. His objective is to find a way to live forever, and in pursuit of his goal he creates an android David, and acknowledges that the android is as close to a son as heâ€™ll ever have.
Weyland is 101 years old and in poor health, and it appears he either seeks to find a way to rejuvenate his body or perhaps to live on through the passing of his genes by discovering a cure for his sterility. Thatâ€™s possibly why David, like the Engineers, is interested in human reproductive capabilities and again like the Engineers, conducts reproduction experiments using two other characters as guinea pigs.
Weyland never achieves any of his goals as he is beaten to death by his creator, the Engineer, who uses Weylandâ€™s android David, as the weapon. Symbolically, Weyland's death comes from both sides of the generative spectrum because in life he was sterile and in death, there is only an eternity of nothingness.
In death Weyland finally discovers the answer to one of life's ultimate questions: is there life after death?
The answer is a disappointing "no" because his alien creators are themselves the accidentally evolved products of matter which itself emerged out of the lifeless void.
Movie reviewer Christopher Campbell likened the meaning in "Prometheus" to the searing pain of "extinguishing fire between our fingers." ('Prometheus' Plot: Looking For Meaning Behind Ridley Scott's 'Alien' Prequel,
It is searingly painful because utterly without hope. Life is a mere spark in time book-ended by death. Somehow from death came life, hence back to death it goes. Dreams of immortality are without hope because without Jesus Christ God Himself (John 10:10) death is always the victor.
