Why intelligent life failed to evolve on our moon or on the planets in our solar system?
The conditions on the moon and other planets in the solar system are not those which support life. Only on the Earth is there an atmosphere with the correct balance of oxygen and other gases, and other elements like carbon, the right balance between land mass and water, gravity, and the right distance between the planet and the nearest star, i.e. the sun. On the other planets, including the moon, it’s either too hot, or too cold, or too much gravity, or too little, or too much of the wrong kind of gases, to support life.
