The answer will depend on the level of statistical knowledge that you have and, unfortunately, we do not know that. The regression model is based on the assumption that the residuals [or errors] are independent and this is not true if autocorrelation is present. A simple solution is to use moving averages (MA). Other models, such as the autoregressive model (AR) or autoregressive integrated moving average model (ARIMA) can be used. Statistical software packages will include tests for the existence of autocorrelation and also applying one or more of these models to the data.

Why for a random series the autocorrelation between two observation is close to zero?

A non-zero autocorrelation implies that any element in the sequence is affected by earlier values in the sequence. That, clearly violates the basic concept of randomness - where it is required that what went before has no effect WHATSOEVER in what comes next.
