Do the verses Quran 67:3 and 50:6 suggest that we can see heaven, contrary to the belief that it is unseen?

I heard before we can't see the heaven, but do these verses mean that we are able to? I kind of am having doubts. What is the meaning when seeing how the sky is built? Quran 67:3 > And who created seven heavens in layers. You do not see in the creation of the Most Merciful any inconsistency. So return [your] vision [to the sky]; do you see any breaks? Quran 50:6 > Have they not looked at the heaven above them - how We structured it and adorned it and [how] it has no rifts?
