It seems a moon as large as Earth's is crucial for the emergence of life

‌I was watching a science channel
and it said that Mars originally had a magnetic field, an atmosphere, and water just like Earth
But apparently, it all blew away, and the decisive reason is that its internal core stopped moving
On the other hand, because Earth has a large satellite like the Moon, the tidal forces keep Earth's internal core
constantly moving, which allows the magnetic field to be maintained.
