H. P. Lovecraft
Lovecraft's works are ruled by several distinct pantheons of deities (actually aliens worshiped as gods by humans) who are either indifferent or actively hostile to humanity. Lovecraft's personal philosophy has been termed "cosmic indifference" and this is expressed in his fiction. Several of Lovecraft's stories of the Old Ones (alien beings of the Cthulhu Mythos) propose alternate mythic human origins in contrast to those found in the creation stories of existing religions, expanding on a natural world view.

H. P. Lovecraft [SEP] Religion and superstition
Lovecraft's works are ruled by several distinct pantheons of deities (actually aliens worshiped as gods by humans) who are either indifferent or actively hostile to humanity. Lovecraft's personal philosophy has been termed "cosmic indifference" and this is expressed in his fiction. Several of Lovecraft's stories of the Old Ones (alien beings of the Cthulhu Mythos) propose alternate mythic human origins in contrast to those found in the creation stories of existing religions, expanding on a natural world view. For instance, in Lovecraft's "At the Mountains of Madness", it is proposed that humankind was actually created as a slave race by the Old Ones, and that life on Earth as we know it evolved from scientific experiments abandoned by the Elder Things.
