We all live on a globe, a giant ball. The angles of a triangle on this ball add up to a number greater than ##180°##.
And the amount by which the sum extends ##180°## isn't even constant. It depends on the size of the triangle. The flat triangle with angle-sum ##180°## is the exception, not the norm. The real world is crooked.
