The problem is that you're generalizing questions that science and religion address specifically and separately. "How did we get here?" in a scientific context leads to questions about the physical process of abiogenesis and how that process might be understood, replicated, and tested. "How did we get here?" in a religious context leads to questions about what sort of entity may have been responsible for actuating the physical process of creation and what his/hers/its purpose, if any, was in doing so. Maybe you've had different interactions with religion than I have, but I've seldom seen a religious text or religious scholar attempt to use theological concepts as scientific hypotheses.
You seem to have a lot of idealistic faith in the purity of science versus the corruption of religion. If you'd ever sat in on a local government environmental impact study, or written a research grant application, or read a peer-reviewed defense of a popular hypothesis when challenged by new evidence or experimentation, let alone look back at scientific history and observe the more-often-than-not hostile and stubborn nature of one generation of scientists to the next, you'd develop a new appreciation for the equally corruptible nature of science. Which, when you get right down to it, is reflective of the corruptible nature of human beings in the same manner that religion is. Science is no more or less perfect than theological or philosophical pursuits. At the end of the day, warts and all, they both do the best they can to explain the varying mysteries that plague us.
