Nothing to do with believe. Amino acids have been detected in comets and meteorites. That's one possibility. Then there was the famous Miller experiment in 1952, and I wonder why the anniversary hasn't been appreciated last year. They reproduced the early conditions of the Earth's atmosphere in the lab, put hydrogen, water, ammonia, methane in sterile glas tubes and flasks, heated, cooled, and treated it with electric sparks to copy lightning, and after two weeks of continuous operation, more than 20 different amino acids had been produced. Another theory says that life originated in the smoke stacks of undersea volcanoes, they also generate amino acids.
Anyway, it's established that all the macromolecules necessary for life rise on their own out of anorganic matter by natural processes. Let's take the nucleotides, the RNA and DNA molecules. Adenine for example comes with the simple formula C5H5N5, Guanine adds an O to the group, Cytosine subtracts 1C and 2N from that, they all are similar. The very property of those 4 nucleotides is to form base pairs and stacks, their chemistry forces them to do it.
The origin of life is not a place anymore to look for intelligent design, you have to go back further.
