| Description: | Observations of the universe's earliest luminous structures through both ground- and space-based telescopes are gradually revealing the intricate physical processes that shaped the Cosmic Dawn and the Epoch of Reionization. While recent observations, particularly with the James Webb Space Telescope (JWST), reaching deep into the Cosmic Dawn, represent significant progress, they merely scratch the surface of what there is to discover, offering glimpses of "islands" amidst a vast "sea" of neutral hydrogen. In this presentation, I will discuss the current status of our LOFAR Epoch of Reionization Key Science Program, highlighting our latest advances in setting improved power-spectrum limits on the 21-cm signal from neutral hydrogen. This work not only tightens the constraints on the high-redshift intergalactic medium (IGM) but also marks significant steps forward in our understanding of the data itself. Additionally, I will present highlights from the parallel NenuFAR Cosmic Dawn Key Science Program, which aims to capture the 21-cm signal from the Cosmic Dawn. If time permits, these findings will be put in the context of the Square Kilometre Array (SKA) and our strategies to probe the 21-cm cosmology of the Dark Ages, particularly through space-based receivers like DEX.
