A lot of people do
One sense of it called Spinoza's God

another pantheism

James Lovelock's Gaia principle is also similar in some ways although this does not relate to a concious force
http://en.wikipedia.org/wiki/Gaia_hypothesis
This last one is particularly interesting. Lovelock first proposed that the life forms on the planet it were able to adapt the planets environment to optimise the conditions for life.
Richard Dawkins gave him a lot of stick about it particularly for the lack of a model of how this could occur. Lovelock eventually came back with the notion of "Daisy World"
http://en.wikipedia.org/wiki/Daisy_world (I know wikipedia again!) that provided a model.
Daisy world gave Gaia scientific credibility.
Whichever of these notions you feel closest too (Einstein was a fan of Spinozas God) rather depends on how much conciousness you want to ascribe to this "force"
