We've never seen THIS before - James Webb Space Telescope

So in the concept (or theory) of a ball explosion or one point of origin outward.
How do we know where the Earth is from that point ? Old or Newer ?
Old and Newer does not apply IF the explosion happened all at once.
We only have farther or closer to the origin which is a unknowable fact.
So is "further" away from the point of origin "older" and closer "newer"
This concept makes no sense. The "Big Bang' is just someone's idea anyways...
And to explode in one certain direction makes no sense either....
