How Would You Know There Is Life Out There?

Romans 1:19: Because that which may be known of God is manifest in them; for God hath shewed it unto them.

There are those who are searching for life in outer space. Such groups include SETI – the Search for Extra-Terrestrial Intelligence. But supposing they received a signal from outer space. How would they know, if it was really an intelligence? In 1967, scientists at Jodrell Bank in England picked up regular pulses of radio signals, and they assumed that the signals must be intelligent in origin. In fact, they were of natural origin, caused by the rotation of dense stellar objects, or pulsars. Scientists realized that mere repetition of a signal does not represent intelligence. So, SETI has a definition which insists that observers look for “the existence of coded information on the signal”.

Has any such signal ever been observed? The answer is yes. But such signals have not been found through the telescope, but, rather, through the microscope. Such signals are found in molecules of DNA. DNA contains information, which is known to be highly sophisticated; so much so, that to explain this point further would require many more broadcasts. Yet some biologists have likened the information in DNA to the regularity found in salt crystals. These salt crystals do indeed have regularity, but this is not information.

There is an inconsistency in those, who insist that simple regularity is not information in one context, yet assume that it gives rise to information in another. For us, the information in DNA is what we expect in a material created by God.

Prayer: Thank you, Lord, for Your wonderful Word, which gives light to our path every day. Amen.
