Christianity and the Omnipresent God

Christianity is a sophisticated religion which is about 2000 years old with wide ranging diversity on thought and doctrine on God. Yea God, it has been monopolized by the Christians. It comes with an urgent message of salvation and redemption from "Sin" which is a strange subject on its own. However one is surprised that it took over a million years for the Good News to reach humanity, the homo erectus and other ancestors were left out and it took another thousand years to reach Africa and other parts of the world, still there are places which are not informed/touched by this "News" Given that Christianity is the one and only true religion through access to "God" is made. If we are to follow the attributes of God, one that stands out against a true religion is his omnipresent nature. That is God's presence is felt everywhere, at all times and in all minds. It follows that different contexts/religions/media is valid and competent to comprehend such a being. Also by his nature necessarily infuses an idea of his being to every human culture, religion (any concept of worship), thought/philosophy. That all through time, our ancestors, us and future generation always have from collective memory or individual search, known who God is. Christian doctrines are firm that Jesus is the only way to understand God, consequently Christianity is as a "true" religion worshipping an omnipresent God is certainly on a path of self contradiction and falsehood. Christianity having made claims to comprehend and worship the True God, serves upon itself a note of self invalidation! That's it is a false or confused religion.
