On the Origin of Species by Means of Natural Selection; Or, The Preservation of Favoured Races in the Struggle for Life

i love this book.

I have not gone through the whole book but i studied it partially as part of our curriculam. Here are my thoughts in general and the questions which remains unanswered:
Considering Charles Darwin's theory of 'Origin of Species' true, regardless of scientific and religious contraditions, may still become a powerful evidence and means to advocate the 'struggle for existance' and hence justifying the survival/existance of the fittest/strongest by deploying any means to prove their strength regardless of moral ethics. It is very dangerous since it implies that it is all nature and no God and thus no moral laws needs to be followed.
Darwin's theory talks of natural selection which happens when any external force is applied by nature to find the fittest. This in human culture today has to be more artificial force as it is, and hence, the survival of the fittest shall be dependant on many factors such as education, previous family background, financial health, physical strength, courage, confidence etc physical and emotional factors. What do you think will become of society if it was depending on 'survival of the fittest' theory. Need of fear and love of God comes in picture only if he is considered the creator and sustainer of the creation, else if everything is natural, then we would rather extinct earlier by fighting ourselves only.
Naturalists ask one question very frequently - if God created everything, who created God. My counter question is - if nature created everything, who created the nature. Who devised the natural laws and governs them flawlessly. How nothing can become something without any initial matter? How collission of two non-systematic things create something highly systematic? How copulation of two distinct species can bring a third fertile generation which will survive in the natural selection and will produce more?
Darwin's theory has certain flaws and is apparantly a provisional truth, that is a truth which is a truth unless it is proved a lie. I personally, not being a biologist, but a geologist and spiritual man, am unable to understand how and why should Darwin oppose a creator, whatsoever. In the first place, even if rest of the many things evolved, it is essential to resolve that there was some matter (solid, liquid or gas) from which the whole reactions started. Secondly, considering evolution as a fact should be proven by more than 2-3 evidences or witness; and evolution cannot be proven except one or two fossils found which seem to be in transitional stage. However, this could be a human error also to mix some parts by mistake to understand them so, since there has never been found a replica of such fossils anywhere else ever.
If evolution happens for the existance of the fittest and species struggle and adapt themselves to the natural conditions, why does some of the former speicies remain as it is. Did they manage to exist without any adaptation, if so, why only some of them changed. Example if bear turned into polar bear in polar regions, why there are bears still? If monkey turned into man, where there are monkey's still? If fishes could not survive as fish and had to adapt, why there are fishes still? We can see many thing today right from the older times, but not the strongest animals anymore - dinosours? Were they not strong enough? If so, normally when unicellular organisms became complex later, how the larger animals became smaller again? Ex. The link between birds and reptiles is Archeopterix, which was a very large bird with limbs and jaw, then how did rat evolve. Was there anything so strong about rats that they managed to exist till today while large reptiles disappeared, altogether?
Why there are certain species so beautiful and attractive that they must be killed at the first instance possible- ex peacock. How and why would nature make evolution which makes it more vulnerable. Is sex the only reason? Why are the peahens not beautiful then? Why such a large bird survive on insects etc? There are many such questions which
