Atoms on a round rock

The other movie I watched last weekend was Martian Child. LOVED it!

David: Dennis, can I just say one last thing about Mars…which may be strange coming from a science fiction writer…but, right now, you and me, here, put together entirely from atoms sitting on this round rock with a core of liquid iron held down by this force, that so troubles you, called gravity, all the while spinning around the sun at 67,000 miles an hour and whizzing through the Milky Way at 600,000 miles an hour in a universe that very well may be chasing its own tail at the speed of light. And amidst all this frantic activity fully cognizant of our own imminent demise which is a very pretty way of saying we all know we’re gonna die, we reach out to one another. Sometimes for the sake of vanity, sometimes for reasons you’re not old enough to understand yet but a lot of the time we just reach out and expect nothing in return. Isn't that strange? Isn't that weird? Isn't that weird enough? What the heck do ya need to be from Mars for?
