  "abstract": "We consider the capabilities of ALMA and the ngVLA to detect and image the[CII] 158\\,$\\mu$m line from galaxies into the cosmic `dark ages' ($z \\sim 10$ to 20). 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$\\sigma$. The ngVLA will detect the integrated [CII] line emission from a Milky-Way like star formation rate galaxy ($Z_{A} = 0.2\\,Z_{\\odot}$, SFR = 1\\,$M_\\odot$\\,yr$^{-1}$), at $z = 15$ at a significance of 6$\\sigma$. Imaging simulations show that the ngVLA can determine rotation dynamics for active star-forming galaxies at $z \\sim 15$, if they exist. The [CII] detection rate in blind surveys will be slow (of order unity per 40\\,hr pointing.",
