كتاب الكون لكارل إدوارد ساغان

The great writer talks about this world and its emergence and its creatures created by God to benefit man in various aspects of life. A person has nothing but to initiate action and strive to think and search for what is in the universe and search for data and theories that scientists have imposed from conducting their research and the laws and foundations they have derived from them that led to the development of life.
