The egg did not come first it was the chicken, organisms would evolve into the actuall animalls not their eggs.
The universe is light, dark matter, and more matter (such has the basic compunds which build us) Everything evolves and everything will continue to evolve until the universe ends, even stars plants evolve over time, such as global warming which is Inevitable. If you think about our solar system we are the 3rd plant from the sun, in our galaxy there is probably thousands of terrestrial planets which are this distance from the sun. water, sun and consumption of other organisms make us evolve. So every living thing will evolve. If anyone knows 'M' Theory it says that at the point of our universes creation mass amounts of light, gravity, dark matter and matter, collided in massive waves, creating our universe. This means life exists probably everywhere throughout the universe probably more advanced then our brains can fathom, and only through the process of evolution can we un-lock our mind, un-lock truths. I believe smoking weed enhances these thoughts because imagination is everything.
