The old earth mythologies are much older than that, but Christians just gave an ear to them in the past 150 or so years. Evolutionary philosophy goes back to 1200BC. In its infancy, the idea was birthed from Hindu Brahmin teachings in India. The ancient Greeks took those beliefs and developed them further in 600BC or so. Evolutionary philosophy got a huge boost in the public eye with the false geological belief of uniformitarianism in the 1700s (AD). By the way, the Big Bang idea was developed by a Christian scientist/teacher. Doesn't mean he was right. But yes, there are only two worldviews that exist - God's truth and mankind's 'truth'. I opt for God's truth.
I understand that Tintin and how the New Age/Old Earth Mythologies are just remixes of ancient pagan philosophy and such. In my opinion Hellenism is more influential upon it, it's sorta noticeable when they name dang near everything after Hellenist characters. Merely denoting the old earth mythology/new ager stuff proper didn't really begin as we know it today until about 200 some years ago, particularly becoming in vogue last century.
