By latest estimate... how many billions of years after the Big Bang before life became possible? 2 billion yrs? 5 billion yrs? 7? And why?
Chronos said:The first life on Earth is believed to have originated about 3.8 billion years ago with prokaryotes - most likely cyanobacteria. Multicellular life came much later, beginning about 2.1 billion years ago and critters we would recognize as animals - about 570 million years ago. In terms of BB time, the first life on Earth arose about 10 billion years after the big event. The earth, at that time was only around 700 million years old. Obviously selection pressure was fairly subdued over the 1.7 billion years between prokaryotes and multicellulars and the 1.5 billion year span between multicellular life and animals
dahoa said:Thank you. But I was asking for the first life that is possible in the universe as a whole. For example. 5 billion years after the Big Bang.. can the stars already in a state that can support life? Or in other words, how old could be the oldest possible aliens in any part of the universe?
davenn said:We can only go by what happened on Earth as our guide, since we have no idea if life even exists elsewhere in the universe
dahoa said:Or by the age of the stars... how many years after Big Bang was there stars like our sun?
"Unlocking the Mystery of Life" is a documentary film that explores the scientific evidence and theories surrounding the origins of life on Earth. It delves into the concept of intelligent design and examines how scientific discoveries have challenged traditional evolutionary theories.
The documentary was produced by Illustra Media, a production company that focuses on creating films about scientific and philosophical topics. It was directed by Lad Allen and narrated by John Rhys-Davies.
The film presents evidence from various fields of science, including biochemistry, genetics, and paleontology. It showcases the complexity and functionality of living organisms, as well as the information and design found within their cells, which suggests an intelligent designer.
The documentary does not explicitly support creationism or intelligent design, but it presents evidence that challenges traditional evolutionary theories and suggests the possibility of an intelligent designer. It encourages viewers to consider different perspectives and think critically about the origins of life.
The film presents scientific evidence and theories that have been supported by peer-reviewed research and published in reputable scientific journals. However, it is important for viewers to critically evaluate the information presented and form their own conclusions based on the evidence.
