How and when life first took root on Earth is still not very well understood. We have a relatively vague timeline that indicates life was indeed present on Earth some 4.5 billion years ago but we don't really know what happened before that. Life could have existed for some time by that point, or they may indicate some of the very earliest forms of life. But perhaps more importantly, we still don't know how life formed. Whether it was a spontaneous reaction in a bubbling crockpot of materials in the ocean or the result of life's core ingredients arriving from elsewhere is something that scientists just can't say with any degree of certainty.
Looking for the clues to answer that question often means looking to space and, more specifically, meteorites that may have delivered the building blocks of life billions of years ago. A chunk of rock that slammed into a UK family's driveway probably isn't going to answer that question, but it might provide scientists with some supporting evidence one way or the other.
