Blackholes and Galaxies

I came across this article today in BBC about blackholes existing before galaxies. Here is the link http://news.bbc.co.uk/2/hi/science/nature/7815827.stm

From what I read in the article, it seems that the scientists have spent plenty of time collecting evidence about what came first. Was it the Blackholes? Was it the Galaxies?

Here is my opinion on this:

Lets assume that we want to construct a house. The first step we do is to find some empty land. Then the foundations are laid on this empty land and with the combining of some basic elements and effort we get a complete house. So after all this lets say some one asks you the question as to "What came first the house or the empty land?", what will be your answer? Will anyone say that the house came before the empty land? Similarly there must be emptiness before it gets filled with anything. I dont know why the scientists spent so much time in researching this. Nothing can exist until the emptiness allows us to exist.

One more analogy here is as Bhagwan Sri Sathya Sai Baba Quotes : "KEEP THE MIND EMPTY ONLY THEN CAN LOVE BE FILLED INTO IT "

Thats my opinion on the discussion of "What came first? The Black Holes? The Galaxies?"
