Celestia vs Eigenlayer

I am a noob. As far as I understand, both Eigenlayer and Celestia are trying to solve the same problem (that is, data availability) via different approaches. However, how do they differ fundamentally?

I read some articles online but are really technical. Celestia (as I understood) use light nodes to guess the validity of some information on chain with certain confidence level. Whereas Eigenlayer use liquid stakers' tokens to somehow verify the blocks? (sorry if I'm talking bs here).

Can someone explain intuitively? Moreover, in long run which one would more likely to coexist with Ethereum?
