Opposite of predating
Originally the concept of "atheism" was contributed by the Greeks in 5th Century BCE, and then the words "atheist" and "atheism" were later introduced in the mid-to-late 1580s CE (adapted from the French words "athée" and "athéisme"), almost one century before the words "theist" and "theism" were added to the English language in the 1660s and 1670s CE.
Historically, the derivations from the French language have the notable distinctions of further emphasizing the "non-belief" and "belief" characteristics upon being translated to "athéisme" ("atheism") and "théisme" ("theism"), which in turn also carried forward to the later English translations to "atheism" and "theism" respectively (and continue to exhibit these qualities to this day).
Pre-dating is the period of time before a couple becomes official.
It often includes a significant amount of hanging out, flirting, and often times arouses suspicion amongst friends of either or both parties.
Roughly 2,000 years later, during the 1570s and 1580s, the word "athéisme" was introduced to the French language.
Shortly after that time, the word "atheism" became a part of the English language over the next 5 to 15 years, and long before "theism" was added to the vocabulary (which disagrees with the seemingly-logical assumption that the word "atheism" is dependent on the word "theism").
Conflation between the "a-" prefix and the "anti-" prefix does sometimes occur, but according to the etymology they specifically mean different things.
For instance, the alpha-privative prefix "a-" or "an-" is still used in Greek words to express negation or absence, while the "anti-" prefix partly yet also distinctly in contrast and more actively expresses opposition.
In the case of "atheism" it appears that the meanings began to deviate from a naturally impartial classification to an anti-theistic position, but now that the meaning of the word "anti-theism" is so widely understood this deviation can more conveniently be rectified...In summary, atheism compares in the same way to the actively-held positions of theism and anti-theism (as well as deism, pantheism, etc.). 500 BCE to characterize "atheism" as a position that specifically opposed the existence of deities (a.k.a., "anti-theism").This was most likely due to its popularized use in debates about religion, primarily between Christians and Hellenic Polytheists, where some adversaries accused each other of being atheists as if it was something unacceptable (perhaps in the absence of other more suitable vocabulary like "anti-theist," hence atheism may have been used as a generalized stand-in amidst a less evolved language from ancient times).However, Rovelli and his colleagues suggested that shrinking black holes could not disappear if the fabric of space and time were quantum — that is, made of indivisible quantities known as quanta.Space-time is quantum in research that seeks to unite general relativity, which can explain the nature of gravity, with quantum mechanics, which can describe the behavior of all the known particles, into a single theory that can explain all the forces of the universe.
