Location of The Prometheus Prologue

I'm sure it was meant to be earth. The whole point of the prologue was to show how life began/was influenced on Earth. It wouldn't make much sense to me if it was anywhere else.

Undoubtedly it is Earth. If the Cambrian Explosion took place around 530 million years ago there would be no familiar continents anyway.

As the overhead panning shot goes through its motions you can clearly see grass, and plants already existing prior to the black goo scene. Why kick start life when its already there ? As for Scott speculating that civilisations existed prior to anything we know on Earth, i don't buy it..., a bunch of dumb overgrown lizards left trace evidence, but prior advanced civilisations didn't ? Before anyone gives me any grief about Antikythera mechanisms, or Baghdad batteries, just think about what you are about to post before you post it

What about Baghdad Batteries eh? Surely that explains it!

I don't believe Bagdad Batteries or Antikythera machines date back to over 530 million years ago, and I don't think any fan has even suggested they do.

As for flora being on Earth before the engineer breaks down his body to molecular level. Flora is needed to create the atmosphere into which fauna can be introduced.

Pangæa Earth... The waterfalls resemble the ones in South America, Iguazu. So if the Engineers helped kick start life....it must be for a reason? perhaps to ensure we evolve into the perfect breeding vessel? Homo sapien rather any other homo-species. Once we evolved enough to fly to the stars and contact them, they know we are at the right stage to be impregnated.

The problem with Grass is that Grass is a flowering plant. I know it doesn't look like "flowers" but it is, in fact, flowers, when they sprout their fluffy things that blow seeds on the wind. Fans of dinosaurs will recall that flowering plants did not exist before around 65 million years ago - exactly around the same time that the dinosaurs became extinct. It's one of the mysteries of the history of the Earth - an almost bizarre coincidence of scheduling at least to a casual observer such as myself. Considering the Earth is roughly 4 billion years old, 65 million years ago is essentially nothing. It is certainly not 'primordial' in the sense of being a new planetoid that is devoid of life. After all, Trilobites, by 65 mya, had already come into existence, lived 250 million years (roughly 249.99 million years longer than modern humans) and then been extinct for over a hundred million years. Now it seems to me like if Grass is essentially a 'pretty damned advanced thing' to have on a planet, and the Engineer sequence at the front of the film is taking place on some planet, any planet, then that 'any planet' must have been around quite a while before our sacrificial semi-translucent friend took his last morning cup.

Sorry I'm late. I wanted to clarify that the indistinct smatterings of green seen in the film's prologue are not fields of grass, but they are in fact large expanses of microbial mats and terrestrial cyanobacteria (blue-green algae). The prologue does in fact occur prior to the Cambrian explosion. Microfossils confirm the presence of terrestrial microbes and cyanobacteria prior to the Cambrian explosion. Ridley Scott actually did his homework, and I'm sorry but the sweeping panoramas in the prologue are too fleeting to distinguish let alone confirm that the green you are seeing is grass. I hope this clarifies things a little.

I always thought that the green was lichen To me thery were visiable on the openning scene and just a hint of green in the landing sequence of the Prometheus. I still wonder if there was a evolution connection between our Earth and LV-223. I never saw it as grass..

How come the sweeping panoramas are too fleeting to distinguish grass but slow enough to distinguish microbial mats and terrestrial cyanobacteria (which still exists today, doesn't it?) And what did the jockeys breathe - not much oxygen prior to the Cambrian era?
