  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.
