Razmišljajte ovako. Ako bi vanzemaljac htio shvatiti kako ljudi žive i umiru, a mogao bi nas gledati samo 30 sekundi. Leteći pored Zemlje, slikao bi milijune ljudi.
Think of it this way-- if an alien wanted to learn how humans live and die, but they could only watch us for 30 seconds-- they flew by Earth and they took pictures of millions of humans--
