I'm all for setting the scales infinitely small to discuss because no matter what fraction of time into the future you name, it will never be that time, because the future is any and every time after the present greater than 0.
I don't agree with this though. I would prefer to say the big bang was only a small amount of time or a moment ago, relatively speaking. Yesterday is a definitive term for a 24 hour period of the past and the big bang did not happen within that time frame. Same goes for any measured time, i.e. hour, millisec, etc... If the Universe keeps expanding and contracting then to the universe (or some eternal or ancient being) the big bang may seem like it was only a small moment ago, but not a measured amount of time like an hour which is defined.
