Compilation of Scientific Errors

GROSS ERRORS OF SCIENCE THAT I NOTED [b]1. Taking off your helmet on a foreign environment, despite a breathable atmosphere.[/b] Reason: We know on earth that spores can last millions of years. The smallest biological organism, harmless on an alien planet, could be a devastating pandemic to human beings who lack the evolutionary resilliency to it. When I saw all these "scientists" take off their helmets simply due to breathability, it destroyed the believability. How did the writers overlook this? [b]2. Alien Autoposy without quarrantine.[/b] Lets put the head of an alien being on a table, without environmental quarrantine, and without face masks, without bodily protection, and let me get right up to it so i can smell it. What if this thing died of....get ready...A DISEASE! We already knew these beings died en masse, bodies piled up. For all we know, they died of a horrible disease. Yet she just touches it and smells it and breathes it...no problem. (she even said "he stinks") [b]3. Dumping human DNA into a river, and that somehow leads to the first human.[/b] (Assuming that the opening scene is the seeding of primordial earth) Consider that if human DNA is floating around in water, then how did a human being "come out" of it? Are you saying that what came out of it was an amoeba, and then a slug, and then a jellyfish, and then a snail, and then a lizard-->bird-->dog-->ape--man? Is that what the movie is saying happened? [b]4. Cave paintings when humans came from DNA in a river:[/b] Consider the following: 1. Human beings came about from micro-evolution due to alien seeding on our planet and millions of years of evolution. THEREFORE, 2. How did our early ancestors know the exact location of the alien world? If our ancestors evolved from jellyfish and amoebas that came from alien DNA, by what basis would they know where the star system was? [b]5. Alien locked in a sanitized surgical room grows to 100x its original size without a food source.[/b] How does an organic biological being increase its organic mass in a sterile environment? There is no food in there. Am I supposed to believe this alien is simply feasting on plastics and computer terminals?
