The [CII] line may prove to be a powerful tool in determining spectroscopic redshifts, and galaxy dynamics, for the first galaxies. In 40\\,hr, ALMA has the sensitivity to detect the integrated [CII] line emission from a moderate metallicity, active star-forming galaxy [$Z_A = 0.2\\,Z_{\\odot}$; star formation rate (SFR)= 5\\,$M_\\odot$\\,yr$^{-1}$], at $z = 10$ at a significance of 6$\\sigma$.
