National Geographic reports on the controversy of where our sun originated. In doing so they bring up a couple of the exact variables in order for life to exist.
Mystery Deepens Over Where Sun Was Born: "The key factor is that the sun is currently traveling at roughly 67,000 miles (108,000 kilometers) an hour away from M67.
Pichardo and her team's simulations show that, in the unlikely event of the sun's ejection from M67 at the right place and the right time, the star's speed would have to have been closer to 130,000 miles (209,000 kilometers) an hour—much too fast to ensure the solar system's safety.
At such speeds, "if planets are not kicked out, they can at least be perturbed into noncircular orbits," Pichardo said. "A [roughly] circular orbit is a big reason the Earth is habitable and we're alive today."
If Earth's orbit were more elliptical, the planet would bake when it drifted too close to the sun and then go into a deep-freeze as it moved away, a scenario perhaps too hostile to support life."
Can it be said that National Geographic understands how privledged our planet really is? If they would write about the other variables that happened by chance (sic).
Speed of the sun from other stars at a specific required time
The unique orbit of the earth which original material had to be expelled at the right time and speed
The right distance of the earth from the sun, not too far and not too close
All happened by chance? I don't think so.
