Back in like 2005 or 2006, I remember posting an article to Fark about a company that wanted to make a laptop that had the entire internet cached on it so you could browse the web offline. That was almost 20 years ago and I remember saying "they have seriously underestimated the amount of porn on the internet."
Not necessarily. All we know is that everything seemed to come from a single point, on a cosmic scale. However, at that scale, our entire galaxy would be considered a single point.
What we do know is that everything is expanding, and that it was homogeneous by the point that it cooled enough to cease being a plasma (and so opaque to light). It could have been a vast area that suddenly spawned matter/energy, rather than a single point.
I remember, towards the end of the last millennium, marveling with some friends about an article estimating the current size of all the data on the internet. IIRC, it was in the neighborhood of a couple hundred terabytes. Wouldn't fit on your phone, but there's plenty of data hoarder types who have that kinda storage on the server in their spare room.
English not your first language? No worries, see the "would have"? That phrase signifies a hypothetical - I'll leave you to ponder what hypothetical situation could be meant in this particular case, but spoiler: it involves comparing features of things that were constructed in different time frames.
If we define the size of the Internet as a continuous function, and it started at zero and currently doesn't fit in your phone then yeah, no shit, at some point it fit in your phone.
If it's truly continuous there was an exact point where it would exactly fill up your phone with no room left over.
