No, “loud” is *precisely* what the Big Bang (BB) was definitely _not_.

Contrary to an atomic bomb, the BB was *silent* because there was no medium 
to transport sound yet – gases could not form before 380'000 years *after* 
the BB, when the universal temperature was low enough for that – nor was 
anyone there to hear it anyway.  And it was *dark* because photons did not 
exist until 10 seconds *after* the BB.  (The only similarity between the BB 
and an atomic bomb is high temperature – but the temperature of the universe 
shortly after the BB was millions of orders of magnitude higher than that of 
an atomar explosion, at least 10³² K compared to at most only 300'000 K.)

The BB was the *beginning* of an *expansion* of our *universe*, _not_ an 
explosion of something.

The term was introduced by Fred Hoyle, an English astronomer, to *deride* 
the (now well-confirmed) theory of the expansion of our universe because he 
*doubted* it, and the term stuck.  (Hoyle preferred his Steady State theory 
instead and kept defending it until his death, despite all observations to 
the contrary.)

*Learn* what you are talking about *before* you are talking about it:

That assumption is unwarranted, probably based on your not being a native 
speaker of English (I am not either, but I speak it at near-native level).  
Although it is probably wiser to use the term “human” and “humankind” then, 
“men” can refer to the population of Homo sapiens that identifies themselves 
with the male gender, or to *the species as a whole*, and it did so 
historically.  “mankind” is even universally understood to refer to the 
entire species – past, present, and future.

For example:

| We hold these truths to be self-evident, that all men are created equal,
| […]

  —United States Declaration of Independence

| That’s one small step for [a] man, one giant leap for mankind.

  —Neil Armstrong’s first public words on the Moon
