Learn English – Meaning of “life as we know it”

meaning

What does it mean? There's a movie by this name, and i've heard people saying it often. I have been trying to find its answer but couldn't find any.
A sentence/example would be nice too.

Best Answer

Life in the way which we see/understand it. Or more commonly, as it currently is.

The sentence is suggesting that we do not currently understand something entirely, but have a certain level of understanding. It is giving the context of "life" as it is currently understood. There may be other forms of life we can't even comprehend, or have just never seen. Similarly the concept of life may change over time. Consider bacteria, which is a form of life we simply didn't know about 500 years ago.

A more elaborate example.

Life, as we know it, is hard. Maybe one day, humanity will find a way to make it easier.

The implication is that life may one day become easier, but right now (the way we understand it) it isn't. Alternatively it may have previously been harder

Life as we know it is easy, imagine working in a coal mine 200 years ago!

Again this sentence is using "as we know it" to give the context of "as it is now"
