Science is responsible for the following knowledge about our origins.
We know approximately when the universe began and why it is largely hydrogen. We know why stars form and what happens in their interiors to convert hydrogen to the other elements and hence give birth to chemistry in a world of physics. We know the fundamental principles of how a world of chemistry can become biology through the arising of self-replicating molecules. We know how the principle of self-replication gives rise, through Darwinian selection, to all life, including humans. It is science and science alone that has given us this knowledge and given it, moreover.
