It is up to mankind to embrace the purpose of God Almighty. The Judaism of Moses (peace be upon him) has its rules, perfect in nature, for the people of that time.
Later, it became very heavy and complicated to live by those rules. That is why the Christianity of Jesus (peace be upon him) came to replace the Judaism of Moses.
Slowly, those rules of Christianity became heavier and heavier, and hard to live by for all its heaviness. That is why the Islam of Muhammad (peace be upon him) came to replace Christianity. Islam on the other hand is made for all times from that time on, until the ends of time, for eternity. Indeed, God Almighty intended to end the cycle of prophethood, commissioning Muhammad (peace be upon him) as the very last of all His prophets, with no prophets after him.
The whole of mankind can witness by itself that Islam is able to go throughout the times and ages, for centuries and centuries without any sign of obsolescence. Anything Islam forbids, it is because there is a great benefit for mankind, or other species, in it. This goes for absolutely all the 800 prohibitions of Islam.
One of those things Islam prohibits is to accept religion forcefully. Accepting Islam under compulsion is absolutely rejected: "There shall be no compulsion in [acceptance of] the religion." (The Holy Qur'an, S 2, V 256).
This is the reason for the succession of religions.
