No, the proof is in Scripture.
You've been shown the truth.
The Holy Spirit is received by faith in Christ.
Gal 3-
2 I would like to learn just one thing from you: Did you receive the Spirit by the works of the law, or by believing what you heard?
5 So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard?
Zero reference to water or baptism.
These 2 verses refer to the same subject as Eph 1:13,14
13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,
14 who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.
Water baptism accomplishes 2 things:
1. identifies the baptized with Christ.
2. gets one wet
That's all, folks.

Baptism in Jesus' Name accomplishes two things:
1) remission of sins
2) the receiving of the gift of the Holy Ghost.
'nuff said!
Actually, I will say one more thing.
You may indeed be able to apprehend the Holy Ghost through simple faith and prayer...
However, if you want an absolute promise; so that there is no room for doubt as to whether you may have received a counterfeit,
Be baptized every one of you in the name of Jesus Christ of Nazareth for the remission of sins.
(Acts 2:38-39).
It's as simple as:
"get this one done."
