I saw this sentence in my textbook.
Neil Armstrong was the first man to walk on the Moon.
I have a question. Can't I use simple present tense
“Neil Armstrong is the first man to walk on the Moon”
to talk about a fact?

Using the present simple to talk about an event that took place in the past is called the narrative present, the historic/al present, or the dramatic present usage. See for example ThoughtCo_Nordquist. It is used to add tension to stories, drawing the audience in:
Matt Barratt draws his gun, aims at the figure standing on the chair, and shoots Bobby the Kid in his back.)
and in giving historical data, especially when listing events:
... ... ...
- 19 July. 1545 King Henry VIII looks on as his newly refitted flagship the Mary Rose sinks in the Solent, off England’s south coast, with the loss of 700 lives.
- 20 July. 1588 The Spanish Armada consisting of 130 warships set sail for England from Corunna, a day later than expected due to a storm.
- 21 July. 1969 The Eagle lands on the moon and US astronaut Neil Armstrong is the first man in history to walk on its powdery surface.
- 22 July. 1946 More than a year after the end of World War Two, bread is rationed in Britain. The shortage is blamed upon a poor harvest and drought.
- 23 July. 1940 The Local Defence Volunteers changes its name to the Home Guard. The one million-strong force, which includes many World War One veterans, is intended to form Britain’s last line of defence against the expected German invasion.
- 24 July. 1567 Mary Queen of Scots abdicates after defeat by the Protestants at Carberry Hill, near Musselburgh, East Lothian....
[Historic UK: Historic July] (note the inconsistency)
So, such a usage is certainly licensed. But as always, context is highly important. It would sound distinctly odd to choose the dramatic/historical present rather than past simple to state a past event in most contexts (including conversation and normal prose).
