Of course space is big. It's where we have all our stuff and still it's almost empty. We don't really need all that space. All our stuff could fit in no space at all. At least it used to.
Back then nothing took any time at all. We didn't have any time. Everything(which was probably noting) happened all the time.
Then lots of stuff happened and we had to get time to keep track of it all. It was a good solution. As long as nothing happened it was ok that everything happened at once but when everything started to happen, it was better to spread it out a bit.
Now a lot of time has passed and stuff is really spread out. Those of us that usually stay in places where quite a bit of stuff is closer together, will get used to that. We easily get annoyed, if stuff we want is stored unnecessarily far away. We feel we simply do not need that much time separation before interacting with our destination.
At least we are about medium sized. Not really big and not really small. No matter where you go, you will always be at the center or the observable universe and have your own local time. Not to shabby, if you ask me.
