[Serious] Why are you an Atheist?

[Alex K]

Whoever told you that is lying in order to deceive you. Be wary. They are misrepresenting in oder to sow doubt and lead you into their trap.

What trap? Sow doubt?
What is the actual age of the earth? Can you tell me when the earth was banged into existence within a year let alone a month?

I barely know what month I myself was banged into existence, why should I know it about the earth. Why would you expect anyone to know it? In the case of the earth, the question doesn't even make sense because the formation of the planet in the protoplanetary disk was a slow and gradual process of accumulation of matter, with one particularly big hit among them (Theia). Your question is a bit like asking at what inch precisely do the Rocky mountains start.
Look here, an actual photo of such a protoplanetary disk underway in a different star system:


How you are being tricked: the propagandists in your faith deliberately push you to ask needlessly impossible questions (the dumbest of those is Ken Ham's shtick "were you there") hoping that an unavoidable negative answer will feed your confirmation bias enough to dissuade you from reality and let them insert their lies.
