Keep in mind that Mars and Venus would both be counted as "earth-like exoplanets" if we spotted them from similar distances.

We haven't seen any chemical signatures that are unique to life in any exoplanet atmospheres so far afaik - but that's not saying much since numerous biological processes mirror geological ones but just go faster, at least in terms of processes that produce enough gases to show up in atmospheric absorption spectra.

In short, we have no evidence that cellular life (let alone anything bigger) exists on other planets - but also no evidence that it doesn't, due to the limited abilities of our best instruments.
