What is it with these department head idiots these days?
What shred of evidence does he have to say this?
...many of which may be very similar to our own earth...
Or not!
Even if so, what does that prove? Nothing...
This clown is in charge of something? Seriously!
When NASA talks about planets being "earth-like", they are using the term very loosely.
...many of which may be very similar to our own earth...

I have read that there are over two hundred factors that make life on Earth possible that are unique to this solar system. Having the planet Jupiter scouring the sky of big rocks is one of them. Having our moon (a very weird occurrence if you look how we acquired it) is another.
The point is, When Enrico Fermi asked "Where is everybody?" He was exactly right.
There are not, and cannot be very many worlds with circumstances unique enough to allow intelligent life to develop. Having the right sized planet at the right distance is only ONE of the necessary factors.
Bad headline. He didn’t say that. He was just speculating.
