Sorry no he did not@Peterlag debunked your presentation of the word "form" in his thoughtful response above. You need to address that instead of just disregarding it like it never happened. Since form refers to the physical, outward, appearance then your premise regarding a pre-existence is moot unless you're saying Jesus pre-existed as a literal human, which I don't believe you are.
He expressed his opinion ignored the lexical data and the point of the passage which you do as well
The pre-existence of Christ which is my point, not so much the meaning of morphe
but Morphe

Mk 16:12 ἐν ἑτέρᾳ μορφῇ πορευομένοις
Rick Brannan, ed., Lexham Research Lexicon of the Greek New Testament (Lexham Research Lexicons; Bellingham, WA: Lexham Press, 2020).
μορφή, -ῆς, ἡ, [fr. root signifying ‘to lay hold of’, ‘seize’ (cf. Germ. Fassung); Fick, Pt. i. p. 174; Vaniček p. 719], fr. Hom. down, the form by which a person or thing strikes the vision; the external appearance: children are said to reflect ψυχῆς τε καὶ μορφῆς ὁμοιότητα (of their parents), 4 Macc. 15:3 (4); ἐφανερώθη ἐν ἑτέρᾳ μορφῇ, Mk. 16:12; ἐν μορφῇ θεοῦ ὑπάρχων, Phil. 2:6; μορφὴν δούλου λαβών, ibid. 7;—this whole passage (as I have shown more fully in the Zeitschr. f. wissensch. Theol. for 1873, p. 33 sqq., with which compare the different view given by Holsten in the Jahrbb. f. protest. Theol. for 1875, p. 449 sqq.) is to be explained as follows: who, although (formerly when he was λόγος ἄσαρκος) he bore the form (in which he appeared to the inhabitants of heaven) of God (the sovereign, opp. to μορφ. δούλου), yet did not think that this equality with God was to be eagerly clung to or retained (see ἁρπαγμός, 2), but emptied himself of it (see κενόω, 1) so as to assume the form of a servant, in that he became like unto men (for angels also are δοῦλοι τοῦ θεοῦ, Rev. 19:10; 22:8 sq.) and was found in fashion as a man. (God μένει ἀεὶ ἁπλῶς ἐν τῇ αὐτοῦ μορφῇ, Plat. de rep. 2 p. 381 c., and it is denied that God φαντάζεσθαι ἄλλοτε ἐν ἄλλαις ἰδέαις … καὶ ἀλλάττοντα τὸ αὐτοῦ εἶδος εἰς πολλὰς μορφὰς … καὶ τῆς ἑαυτοῦ ἰδέας ἐκβαίνειν, p. 380 d.; ἥκιστʼ ἂν πολλὰς μορφὰς ἴσχοι ὁ θεός, p. 381 b.; ἑνὸς σώματος οὐσίαν μετασχηματίζειν καὶ μεταχαράττειν εἰς πολυτρόπους μορφάς, Philo leg. ad Gaium § 11; οὐ γὰρ ὥσπερ τὸ νόμισμα παράκομμα καὶ θεοῦ μορφὴ γίνεται, ibid. §14 fin.; God ἔργοις μὲν καὶ χάρισιν ἐναργὴς καὶ παντὸς οὑτινοσοῦν φανερώτερος, μορφήν δὲ καὶ μέγεθος ἡμῖν ἀφανέστατος, Joseph, c. Ap. 2, 22, 2.)*

FORM (Noun)
1. morphe (μορφή, 3444) denotes “the special or characteristic form or feature” of a person or thing; it is used with particular significance in the NT, only of Christ, in Phil. 2:6, 7, in the phrases “being in the form of God,” and “taking the form of a servant.” An excellent definition of the word is that of Gifford: “morphe is therefore properly the nature or essence, not in the abstract, but as actually subsisting in the individual, and retained as long as the individual itself exists.… Thus in the passage before us morphe Theou is the Divine nature actually and inseparably subsisting in the Person of Christ.… For the interpretation of ‘the form of God’ it is sufficient to say that (1) it includes the whole nature and essence of Deity, and is inseparable from them

Morphḗ in Phil. 2:6–8 presumes an obj. reality. No one could be in the form (morphḗ) of God who was not God. However, morphḗ is not the shaping of pure thought. It is the utterance of the inner life, a life that bespeaks the existence of God. He who had been in morphḗ Theoú, in the form of God, from eternity (John 17:5
