When we ingest other living things, the DNA of those living things (fruits, vegetables, nuts, meats, etc.) just happens to be compatible with our DNA so that cellular respiration can take place. If it were not for the fact that our DNA is so akin to all other living things, we could not eat. If we could not eat, we would die.

Is the process of eating and cellular respiration the result of a mere fluke of evolution? Alternatively, could it be that a common Designer made certain that the process of eating and cellular respiration would function in such a precise and perfect manner? Which answer appears to be the most probable to you?

If the supposed cosmic and random happenstance of evolution was the real reason that all living things exist, why, when, and how did this happenstance mechanism decide that living things needed to eat anything in the first place? Would it not be odd that evolution should come up with the idea of food and energy creation through cellular respiration?

Cellular respiration is an astoundingly complex, energy-expending system. Yet in order for life to be sustained, living things must have other living things to ingest. What an odd thing for a mere cosmic coincidence to develop, by random generation. Is it not a strange convenience for evolution that all living things have such unimaginable DNA similarity that cellular respiration is possible?
