I mean the moon and sun rather, and what changes about them to change the Earth's precession. Sorry

If the Earth's precession is due primarily to the sun and moon; and the moon's orbital eccentricity is relatively stable though the moon's distance from the Earth is increasing; what is it about the influence of the Earth and sun that changes the Earth's precession ?

I watched a program that said that some of Earth's past climate change was due to variations in Earth's orbit and precession due to the the gravitational perturbations caused by Venus and Jupiter. Why would that be so? I know that the orbits of the planets are eliiptical generally and they...
