No. I have played "Crazy Eights", though. Do you normally put a question mark in that game’s name (and then not put the one for the actual question being asked)?
This quiz really should accept "milliard" for the Earth population question as eight billion is the number of seconds in 252,368 years! (Whereas eight milliard seconds is only 252 years!)
I don't know if you're joking or not, but there literally is a different definition of "billion" that has three extra zeroes. The short scale defines a billion as 1,000,000,000 (10^9, or one thousand million), while the long scale defines it as 1,000,000,000,000 (10^12, or one million million. Different countries use one, the other, or both of these, while some just don't use the word "billion" at all. The US adopted the short scale (taking it from France, who now uses the long scale), but the UK used the long scale until 1974, when it officially switched over to the short scale. It's... complicated.
Yes, the long-scale one. Just because the USA (and most of the UK) uses the short scale does not mean that the long scale completely ceased to exist. The vast majority of Europe still uses it, as do sizeable portions of South America and Africa.
Even Canada uses it alongside the short scale (not really sure how you avoid ambiguity when using both, but OK).
When my dad was born, it was 3.4 billion
When my grandad was born, it was 2.2 billion
Now it is over 8 billion, its a crazy world we're living in
