But that assumes that the complex life would have been animal. Plants do not need an oxygen rich environment, in fact, they perform better in an oxygen deficient environment. So, again, why didn't plant life explode in that early environment? (Bear in mind that I do believe plants came first an in great quantities long before animals, I am just questioning the huge time frame for the move from simple to complex plant organisms.)
