Cosmos: A Personal Voyage (Documentary; 1980)
Creator, Presenter: Carl Sagan
It all probably started over 13 billion years ago. A mammoth explosion which sent energy expanding across the universe gave light and mass. This expansion of space after the blast, by all accounts, is likely to be still ongoing as seen by the Doppler effect visible in the telescopic visualisation of distant stars. In cosmic terms, time probably started at that juncture. Then there was nothing for a very long time. Slowly with the cooling of the system, galaxies and stars came around. The earlier stars had short shelf lives. Their burning out of hydrogen fuels gave rise to other heavier atoms and supernovas that became the seed of our existence.
With carbon and oxygen came the blueprint of existence, water. By trial, chance and selection, the seed of life began. Slowly unicellular, then multicellular and complex creatures formed. DNA was found by Nature for continuity of life. With time a primitive reptilian brain evolved. As reptilian started becoming land creatures, some species developed more complex brain and a conscience.
These species of creatures turned out to be the most successful of nature's creations. They started exploring beyond their backyards. Some, however, refuse to use their new found neo-frontal cortex for the betterment of all of the universal's accidents but instead feel contented to let their actions be dictated by the primitive reptilian brain.

They refuse to see their short-sighted view of instant short-term gratification. They fail to look at the fate that may befall them when deadly nuclear arsenals are hurled at each other. The uninhabitable nature of our neighbouring planets in the solar system should forewarn our leaders of the future that awaits us.
For times immemorial, people have shunned from knowledge, critical thinking and use of science to learn about ourselves. Again and again, the wealth of knowledge and scientific discoveries have been destroyed in the name of nonsensical belief and in the haste of wanting to enrich themselves and usurping power. Events in Alexandria and Nalanda are the testimony of these atrocities.

We, as human beings, do not indeed have the higher intelligence to live together in harmony with possible other life forms in the Universe. Talking about the possibility of finding another lifeform in the Cosmos, it appears like a Herculean task. We are however making strides towards this end. Multiple probes and spacecraft are apparently showing positive signs, according to scientists. We are working towards 'contact', not now, but perhaps for generations to come. The Universe is, after all, hell of a big space.
