Here’s what Samantha Rolfe. Lecturer in Astrobiology and Principal Technical Officer at Bayfordbury Observatory, University of Hertfordshire said six days ago:
“Life moves, it grows, it eats, it excretes, it reproduces. Simple. In biology, researchers often use the acronym "MRSGREN" to describe it. It stands for movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.”
“But Helen Sharman, Britain's first astronaut and a chemist at Imperial College London, recently said that alien lifeforms that are impossible to spot may be living among us. How could that be possible?"
Rolfe also says that an “alternative (but imperfect) approach is describing life as ‘a self-sustaining chemical system capable of Darwinian evolution,’ which works for many cases we want to describe.
Yes, this brings Mr Darwin in the equation. according to the evolutionist’s reason, if life is formed by creation, it isn’t life!
She also thinks that tis life is "based on silicon rather than carbon. after all, “90% of the Earth is made up of silicon, iron, magnesium and oxygen, which means there's lots to go around for building potential life.” She thinks that “silicon is similar to carbon, it has four electrons available for creating bonds with other atoms. But silicon is heavier, with 14 protons (protons make up the atomic nucleus with neutrons) compared to the six in the carbon nucleus. While carbon can create strong double and triple bonds to form long chains useful for many functions, such as building cell walls, it is much harder for silicon. It struggles to create strong bonds, so long-chain molecules are much less stable.”
She also says, “Life on Earth is fundamentally different from the bulk composition of the Earth, ” Nature is adaptable – se might see life on Saturn's moon Titan or somewhere else.
