It's simple...the singer is recalling first love and intimacy in the simplicty of pure nature. Later, life gets complicated, but it all boils down to love/sex between a man and a woman, which leads to procreation. This is what everything else is for (jobs/wars, etc). He is now a grown and experienced man with a wife and child. This is very much related to his first love...he is sowing his seed again. This song is about life, love, nostalgia, that sort of thing.
