It is a state at a time we have chosen to calculate the state at other times from. Later or earlier. Initial in the sense of calculation. In the case of the BB, the initial state is the present. Just like when calculating the previous appearances of a comet.
Evolution predicts the spread of traits that enhances the spread of our genes.
But the main problem is the equation of expansion with relative velocity. Since expansion is even, distance between us and these points grows with 0.4c, 0.8c and 1.2c. But this doesn't mean that the source of all that energy was work. Surely we don't need to wait all too long.
