Life has no single purpose, people may think so but they are deluded in their thoughts. We all have our own purpose in life, some may find it and others may not but that's besides the point.
Is there is no one purpose, there is no single truth. And if there is no single truth, then this entire universe is nothing but chaos and all our lives are completely meaningless.
Do you believe there are absolute truths in this universe?
Two: he can decide whether he wants a banana or something else. Using your logic, humans do not have free will either, we do things out of necessity, to get money to buy food water, and support families. If I throw you on a deserted island, you will act the same way as the monkey to survive, this does not mean I have deprived you of free will. Humans are not that special.
Three: It's not wise in our social environment. Yes you can make them whatever you want them to be, as long as you survive and are satisfied.
Four: If you refuse to read the things that will give you the information I am going to spend my time giving you, then I will not even bother. They are theories because maybe they have exceptions, but they have been extensively verified with experimentation and most of the time work. Random processes with no coherent structure? First off there is nothing random in nature, it may seem random as there might be a large amount of variables. The structure is coherent, DNA for example is copied in the same manner in most cells, cells have similar structures, etc etc.
One piece of evidence for macro evolution: Homologous and Analogous Structures.
Homologous structures show us that all of the shown species once had a common ancestor, because obviously their bone structure is very similar, and for common ancestors of lets say cats and humans have same similarities. These structures have different functions though.

Analogous structures show that even when animals do not have the same common ancestor similar pressures in nature will lead to population gaining structures with the same function.

Two: I might act the same way as a monkey would on a deserted island, but only in the survival aspect. What about some abstract emotions (things more complicated than just happiness, anger, or sadness)? What about conscience? What about choosing to either survive or to kill myself? These wouldn't plague a monkey because a monkey only cares about surviving. A human has much more to think about.
Three: I asked you this earlier (I got no response), so I'll ask you again:
If happiness is what we make it, and happiness is our ultimate goal in life, should we not be allowed to pursue that happiness, whatever it may be, no matter the consequences to others?
Four: I refuse to read things that will give me false information. I don't mind at all if you show me something that has correct information and doesn't show theories as facts.
As for your evidence for evolution, I will do more research. I will ask one question though, just out of curiosity: does similarity prove evolution? Could not similarity also prove that all was made by the same Designer? I do not know of all the similarities between creatures, but I do know that there are many differences. I also know that there are many supposed exceptions as well. Remember, even if there is a single true exception to evolution, the whole theory falls apart, as with any other theory. The premises must first be correct in order for the conclusion to be true.
If you want an "exception", here is an example: the bombardier beetle. http://www.answersingenesis.org/articles/cm/v12/n1/amazing-bombardier-beetle
Yes, the reference is from a Creationist-based website, but I want you to look at the facts for yourself instead of coming to a quick conclusion.
In the end though, evolution doesn't bother me as much. Evolution is what happened after the beginning. Although I don't believe in it, it doesn't undermine the possibility that there was a God who set evolution in motion at the dawn of time (again, I don't believe this either, but you get my point). What is more important here is the beginning of the universe and our purpose here on earth. Everything else comes second.
