Anything that can change still experiences “before”, “now”, and “after”.
Since you cannot be in two places at once, you cannot see yourself, your life, on earth unfolding (by the way, thinking you could do that would also mean there is the experience of time in heaven).
Only God is outside of time, because all is simultaneously present within him. Anything not God (created) has movement, and therefore experiences time, including heaven.
If you recall from the book of Revelation, the Saints under the Altar in Heaven asking “How long…?”
God, himself, being timeless, does not “watch our lives unfold”, but knows them in their entirety in an instant, fully complete and always, as if you might imagine a 4 dimensional snapshot, and the snapshot (you) are alive to him. He sees you all simultaneously, but you see him a vast number of times from your snapshot looking back at him with varying understandings of who and what you are seeing. And both of you are happy to know each other and be together.
