A core tenet of science is that these kinds of calculations and theories are disproved and found to be incorrect over time - either that or they are expanded and worked on. A millennia ago, people just like you were claiming indisputable proof that God made it so that the Earth was literally in the centre of the universe. Now we've just moved on to trying to twist it around what we know and grasp today. It is still humongously more likely that either the particular individual in your quote got his calculation wrong or that we simply haven't really found out just exactly how large or how old the universe really is, than it is likely there is a deity.
That would be agnosticism, something I'm signed up for myself. (There are several bands of agnosticism, from the 'I sort of believe in Jesus' to the other extreme end of 'I don't think Jesus or God exists at all, but SOMETHING had to start this whole existence... somehow')
