Unlike the generally accepted theory, humans did not descend from the ape or any other animal.
Billions of years ago when Earth’s crust solidified, plants appeared, followed by animals, and finally by humans.
Evolution certainly took place from plants to humans, but it was only their forms that evolved. The human spirit descended only when a form that suited it emerged.
This can be likened to a new house owner who takes possession of a house only once it has finished being built for them. It’s not the house that produces the owner, they are not created by the walls of the house! They arrive from somewhere else and do not move in until the house is ready.
In the same way, when the spirit found a body capable of receiving it and also the right conditions to manifest through this body, it descended from the heavenly regions and, as it has done for millions of years now, it keeps descending. The evolution of forms was necessary for the involution of spirit to take place.
