The odds of all you wrote for a planet like ours are “astronomical “ lol.
Seriously, the right distance from a small star, water level, magnetic poles , atmosphere...slim to none.
Furthermore, scientists, who promote the theory that a collision between Earth and a Mars-sized planet led to the formation of Earth’s moon (and its contribution to maintaining life on Earth), must acknowledge that a factor for a similar event (and its physical parameters) occurring for a planet in a suitable solar system elsewhere in the galaxy must be included in the probability of carbon-based intelligent life on that planet.
