No, you have yet to prove that tongues is NOT speaking to God/praying in the spirit/ blessing in the spirit! You twist the scriptures to fit your unbelief!
"Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which
cannot be uttered.". Romans 8:26
Many charismatics have used Romans 8:26 as a proof text for tongues, but all Romans 8:26 proves is that the Holy Spirit intervenes in prayer, it says nothing of tongues and in fact, what they miss is that what the Spirit is doing
CAN NOT BE UTTERED. Since tongues is an utterance, then Romans 8:26 is just one verse that proves that tongues is not a prayer language.
Furthermore, the "glossolalia" in 1 Cor 14 itself means "foreign language" not heavenly language:
"Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak
in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans?And how hear we every man
in our own tongue, wherein we were born?
Parthians, and Medes, and
Elamites, and the dwellers in Mesopotamia, and in
Judaea, and
Cappadocia, in Pontus, and Asia,
Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear
them speak in our tongues the wonderful works of God." Acts 2:6-11
The tongues were recognizable foreign languages.
One of the last things Jesus said to His disciples was Go ye into all the world and preach the gospel to every creature. The resurrection of Christ was fresh news and needed to be broadcast without delay. Problem is how do you do that since everyone speaks different languages and it often takes years to learn a different language. God altered their language, problem solved.
In Babel, God divided their language so they could not work together to conspire against Him. Gen 11:7. In the church, God united their languages so that the gospel could be given in languages that the hearers knew and understood.
Thus, tongues is not and has never been a "prayer language".
