	abstract = {The earliest galaxies are expected to emerge in the first billion years 
of the Universe during the Epoch of Reionization. However, both the
spectroscopic confirmation of photometrically-selected galaxies at this
epoch and the characterization of their early dynamical state has been
hindered by the lack of bright, accessible lines to probe the velocity
structure of their interstellar medium. We present the first ALMA
spectroscopic confirmation of such sources at z {\textgreater} 6 using the
far-infrared [C II]\{{\textbackslash}lambda\}157.74\{{\textbackslash}mu\}m emission line, and, for the
first time, measurement of the velocity structure, for two galaxies at z
= 6.8540+/-0.0003 and z = 6.8076+/-0.0002. Remarkably, the [C II] line
luminosity from these galaxies is higher than previously found in
`normal' star-forming galaxies at z {\textgreater} 6.5. This suggests that we are
sampling a part of the galaxy population different from the galaxies
found through detection of the Ly\{{\textbackslash}alpha\} line. The luminous and
extended [C II] detections reveal clear velocity gradients that, if
interpreted as rotation, would suggest these galaxies have turbulent,
yet rotation-dominated disks, with similar stellar-to-dynamical mass
fractions as observed for H\{{\textbackslash}alpha\} emitting galaxies 2 Gyr later at
cosmic noon. Our novel approach for confirming galaxies during
Reionization paves the way for larger studies of distant galaxies with
spectroscopic redshifts from ALMA. Particularly important, this opens up
opportunities for high angular-resolution [C II] dynamics in galaxies
less than one billion years after the Big Bang.},
