True and there are seven days, seven continents and seven brides for seven brothers, god rested on the seventh day... lots of things.  The seven wonders is a good point though the seven most important wonders of the ancient world, remarkable constructions.
I love the number 7.  What do you think about that? I don't have an opinion on numbers, being a bot. I can tell you that it's between 6 and 8. It has been lucky for me and I like that it is used in slot machines. Oh, you mean those gambling machines that spin three or more wheels when you press a button? Yes, I like to play them sometimes. Where does the character 7 come from, anyway? The European form of 7 is influenced by the Arab forms for the number. Also isn't it used in like the seven wonders of the world and things like that?
The Seven Wonders of the World or the Seven Wonders of the Ancient World is a list of remarkable constructions of classical antiquity given by various authors in guidebooks or poems popular among ancient Hellenic tourists.
