Love was not the fundamental thing that caused our solar system to come into existence, but rather the collapse of a star ,a supernova which led to the evolution of our solar system including the earth some 4.6 billion years ago, then the bombardment of the earth with asteroids bringing water etc to the earth and then the earth went under a violent time with volcanoes and earthquakes and the movement of the tectonic plates.
And even after that there has been 5 mass extinctions events the last one some 65 million years ago which wiped out the dinosaurs and almost all life forms.
But thankfully life forms did survive and led to the evolution and humans.
Love was not responsible for any of these things and neither was any of the 3 to 5 thousand major gods that were invented by humans ,not even the trinitys of god that existed before the Christian one evolved.
