Animals are only designed for reproduction. All just to sustain the species and no love connections. Are we just animals like our atheists want us to think? Does sex not carry any other feelings other than reproduction?
Agree with your post. I just had a passing comment. I do think that animals are capable of showing a semblance of love, and even a semblance of marriage as God designed it in some species, though not to say that they do feel or exemplify either to the extent that humans should and do. One example of a species that mates for life with one partner is macaw parrots of varying types. They even have a lifespan similar to people, living an average of 80 years. Some parrot species have been known to die of what is described as depression after the loss of their life long mate.
Also brought to my mind are the pets/companion animals that show obvious grief when they have lost a family member, regardless of what species that family member was (human, another pet, etc). I would call that a form of love and greater emotional awareness than an unthinking being that lives only to eat, mate, and sleep.
In short, I think that God's creation is very interesting and there's a lot that we don't know about it, including animals; and also that I don't think the atheists are right about animals either.
