  • Did the genesis of life occur just after the Big Bang, almost 14 billion years ago? February 5, 2014 at 9:07 am

    After last night’s Bill Nye vs. Ken Ham (evolution vs. creationism) debate, it seems fitting to start the day with new research from a Harvard astrophysicist that suggests the first life in the universe may have emerged just 10-20 million years after the Big Bang. This is a few billion years before most scientists believe that the universe had suitable conditions for the genesis of life. If life really did emerge way back then, and then continued to travel through space on the back of asteroids and other interplanetary debris, it would seem almost certain that a) Earth was not the home of the universe’s first life, and b) life on Earth arrived on the back of an asteroid.
