The diverse life on Earth, our perfect ecosystem, and our incredibly complex body and mind is more than enough proof that a Creator does exist. How? The water cycle and how this provides enough water to sustain our existence on Earth. The human body with all its organs working in tandem most of them on autopilot. The diverse and incredibly voluminous amount of animal life found on Earth with different characteristics. The Earth being perfectly positioned from the Sun so life can thrive and our moon which provides nightlight and balances the elements so life can thrive in and out of the sea.
The evolving of life on Earth does not automatically lend itself for concrete proof of a divine Being having created everything but it sure closes the window or at least makes it very narrow for all of these things to have happened by complete coincidence. Ask any scientist to estimate the chances of the aforementioned happening and it becomes unrealistic.
And if a divine Being does exist and we have been told about him in the only book to ever survive this long and be the most widely publicized and printed book in the history of man, there has to be some credibility to this divine Being having a Son named Jesus who later on became the Christ.
