“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”

― Arthur C. Clarke

This week in the news, scientists announced they have detected gases on a distant planet that are the byproduct of organic life. From an article on BBC

K2-18b is two-and-a-half times the size of Earth and is 700 trillion miles, or 124 light years, away from us – a distance far beyond what any human could travel in a lifetime.

JWST is so powerful that it can analyse the chemical composition of the planet’s atmosphere from the light that passes through from the small red Sun it orbits.

The Cambridge group has found that the atmosphere seems to contain the chemical signature of at least one of two molecules that are associated with life: dimethyl sulphide (DMS) and dimethyl disulphide (DMDS). On Earth, these gases are produced by marine phytoplankton and bacteria.

Prof Madhusudhan said he was surprised by how much gas was apparently detected during a single observation window.

“The amount we estimate of this gas in the atmosphere is thousands of times higher than what we have on Earth,” he said.

“So, if the association with life is real, then this planet will be teeming with life,” he added.

This revelation should not be a surprise to Mormons. We’ve always believed that Elohim made “worlds without numbers” ( Moses 1:33 ) In 1996 then Elder Russell Nelson said in General Conference that there were “infinite worlds”. To me the word “worlds” here mean populated planets, not just planets like Mars, and the trillions of others in the universe (see my post here on the number of celestial bodies)

Lets imagine what it would be like if we definitively discovered life on another planet. Mormons would rejoice at the validation of the Book of Moses. They would expect whatever life was on that plant would be in the likeness of God, and therefore look like homo sapiens on Earth.

How would the Church explain in a theological sense life forms that were NOT like us on Earth? Maybe they could say that humans have not been put on that planet yet? But what if the lifeforms were way more advanced that humans on earth. What is God waiting for? What is the purpose of these advanced life forms? God obviously created them, as he did everything in the universe. Maybe they are the real image of God, and we are an early failed prototype?

Your thoughts on the news this week, and the possibility that there is life relatively close (astronomically speaking) to Earth?

What is more terrifying to you? They we are alone in the Universe, or we are not?
