You're in for a lot of shocks then. The earth revolving around the sun is a matter of mathematical economy, you can just as easily assume the sun rotates around the earth, if you are willing to do way more math in predicting orbital mechanics (way less, in some cases). The assumption is arbitrary, and there's nothing in the overall shape and structure of the universe, that we can now perceive to suggest why you should one assumption to another. The earth might very well be the center of the universe, for ought you can tell from measuring the outer boundaries of the universe. If you have a binary star, which one is in orbit around the other?
As for the earth being round, it's not, it's not spherical by a long shot either.
The Theory of gravity is usually cited by folks of your opinion as the flagcarrier of proven natural science theories, but gravity is in far worse shape now than evolutionary theory, by a long shot: it is reeling from the quantum gravity dilemma, it's conspicuous subnuclear flightiness, the dark matter problem, the outer orbits problem, and recently, because of anomolous navigational behavior by artificial objects leaving our solar system.
