The things is, we can explain how a cellphone arose but we cannot explain how DNA arose, or just how a heart would gradually form by random mutations. BIG difference!
What do you mean "we cannot explain how DNA arose?" Are you saying that we don't understand the bond affinity for nucleic acids in water? Are you saying that we don't understand the prevalence of nucleic and amino acids in places from nebulae to earth to every planet in the solar system?

Are you saying that we don't know the nature of the peptide bonds in proteins or the bonds in a chain of nucleic acids? Are you saying that we don't understand that the bonds have much longer persistence times when not exposed to raw solutions like sea water? Are you saying that we don't know about liposomes that spontaneously form in water due to hydrophobic interactions and how nucleic acid chains could be naturally selected for just by diffusing into a lipid vesicle and finding protection from destructive enzymatic activity?

Wouldn't it make sense that nucleic acid chains (which spontaneously form in the presence of raw nucleic acids) would not be naturally selected simply through the destruction of NAs that did not diffuse randomly into vesicles?

Do you know anything about carbon chemistry? Thermodynamics? The time scales involved since the beginning of the earth? The constituent components on the earth?

Are you saying that there needs to be a supernatural notion about the origin of life? Are you saying that, in spite of all we know about the above topics, that it is implausible that life originated through successive selection by natural pressures of populations of randomly assembling chemicals?

What exactly is your problem with the notion that natural pressures rectify otherwise random processes? This seems to be a CLEARLY understood principle. For example, it's implemented quite well in games of poker (substitute natural pressures for human mind). Randomness is rectified in a certain direction by an external force.

Of course, there need be no purpose to such a guiding force... Hence the diversity of life for whatever nook it arose in.

Do we not know the specific details about the process of the initiation of life? Sort of.

Is it possible to know exactly what happened? No... It's what's called an irreversible process. MANY options could lead to this current outcome so it's not possible to follow it back in a straight/deterministic line.

Does our lack of the details of exactly how it happened mean that we are somehow lacking understanding about the thermodynamics of organic systems?

No.

Your common sense is fairly common. Uninformed about thermodynamics and biochemistry. Quit arguing out of ignorance. Your stance is basically "I don't know how it occurred, therefore, god must have done it." It's a stupid stance that does nothing but close the mind.

Work with what we know. Precede your hypothesis creation by observation!
