Bring the data from several lists to a single lists

I cant find any good information on how to do this. My situation is this

I have a site collection and it has 10 subsites each subsite have the same list with different data,  The layout and columns of all these lists are the same. Our current Farm is SharePoint 2007

What i would like to do is create a single list that combines ALL these lists and then display this merged list on a page.

is this request can be done? If so how?

Thanks in advance
