“Going to it is like making an archaeological dig into the history of our solar system,” he added. “We’ve never been to anything like this.”
Wait???
We’ve been living on an “object” that supposedly was created during that same period of time, or around 4 billion years ago. We’ve already been discovering and investigating and exploring and studying and documenting and actually living on an “object” like the “Ultima Thule”, but, ours is just bigger and contains air and oceans and life-forms of all kinds.
But, it’s okay to be hyperbolic about something that far away, but, it’s basically the same kind of building blocks that went towards creation of our planet.
Their point is that, unlike the Earth which has been bathed in strong solar energy and all kinds o, UT has been preserved in deep space since it formed.
